+//
+// This file defines nearly all constructors and operators for built-in data
+// types, using extended language syntax. In general, compiler treats
+// constructors and operators as ordinary functions with some exceptions.
+// For example, the language does not allow functions to be called in
+// constant expressions - here the exception is made to allow it.
+//
+// Each implementation provides its own version of this file. Each
+// implementation can define the required set of operators and constructors
+// in its own fashion.
+//
+// The extended language syntax is only present when compiling this file.
+// It is implicitly included at the very beginning of the compiled shader,
+// so no built-in functions can be used.
+//
+// To communicate with the implementation, a special extended "__asm" keyword
+// is used, followed by an instruction name (any valid identifier), a
+// destination variable identifier and a list of zero or more source
+// variable identifiers.
+//
+// A variable identifier is a variable name declared earlier in the code
+// (as a function parameter, local or global variable).
+//
+// An instruction name designates an instruction that must be exported
+// by the implementation.  Each instruction receives data from source
+// variable identifiers and returns data in the destination variable
+// identifier.
+//
+// It is up to the implementation how to define a particular operator
+// or constructor. If it is expected to being used rarely, it can be
+// defined in terms of other operators and constructors,
+// for example:
+//
+// ivec2 __operator + (const ivec2 x, const ivec2 y) {
+//    return ivec2 (x[0] + y[0], x[1] + y[1]);
+// }
+//
+// If a particular operator or constructor is expected to be used very
+// often or is an atomic operation (that is, an operation that cannot be
+// expressed in terms of other operations or would create a dependency
+// cycle) it must be defined using one or more __asm constructs.
+//
+// Each implementation must define constructors for all scalar types
+// (bool, float, int).  There are 9 scalar-to-scalar constructors
+// (including identity constructors). However, since the language
+// introduces special constructors (like matrix constructor with a single
+// scalar value), implementations must also implement these cases.
+// The compiler provides the following algorithm when resolving a constructor:
+// - try to find a constructor with a prototype matching ours,
+// - if no constructor is found and this is a scalar-to-scalar constructor,
+//   raise an error,
+// - if a constructor is found, execute it and return,
+// - count the size of the constructor parameter list - if it is less than
+//   the size of our constructor's type, raise an error,
+// - for each parameter in the list do a recursive constructor matching for
+//   appropriate scalar fields in the constructed variable,
+//
+// Each implementation must also define a set of operators that deal with
+// built-in data types.
+// There are four kinds of operators:
+// 1) Operators that are implemented only by the compiler: "()" (function
+//    call), "," (sequence) and "?:" (selection).
+// 2) Operators that are implemented by the compiler by expressing it in
+//    terms of other operators:
+//    - "." (field selection) - translated to subscript access,
+//    - "&&" (logical and) - translated to "<left_expr> ? <right_expr> :
+//      false",
+//    - "||" (logical or) - translated to "<left_expr> ? true : <right_expr>",
+// 3) Operators that can be defined by the implementation and if the required
+//    prototype is not found, standard behaviour is used:
+//    - "==", "!=", "=" (equality, assignment) - compare or assign
+//      matching fields one-by-one;
+//      note that at least operators for scalar data types must be defined
+//      by the implementation to get it work,
+// 4) All other operators not mentioned above. If no required prototype is
+//    found, an error is raised. An implementation must follow the language
+//    specification to provide all valid operator prototypes.

+ *
+ * when modifying or extending this file, several things must be taken into consideration:
+ * - when adding new operators that were marked as reserved in the initial specification,
+ *   one must only uncomment particular lines of code that refer to operators being added;
+ * - when adding new shader target, one must reserve new value for shader_type register and
+ *   use it in .if constructs for symbols that are exclusive for that shader;
+ * - some symbols mimic output of other symbols - the best example is the "for" construct:
+ *   expression "for (foo(); ; bar())" is seen as "for (foo(); true; bar())" by the output
+ *   processor - hence, special care must be taken when rearranging output of essential symbols;
+ * - order of single-quoted tokens does matter in alternatives - so do not parse "<" operator
+ *   before "<<" and "<<" before "<<=";
+ * - all double-quoted tokens are internally preprocessed to eliminate problems with parsing
+ *   strings that are prefixes of other strings, like "sampler1D" and "sampler1DShadow";
