- * Represents a function that can be used in an expression.

- * A function is defined by two PHP callables. The callables are used
- * by the language to compile and/or evaluate the function.
- *
- * The "compiler" function is used at compilation time and must return a
- * PHP representation of the function call (it receives the function
- * arguments as arguments).
- *
- * The "evaluator" function is used for expression evaluation and must return
- * the value of the function call based on the values defined for the
- * expression (it receives the values as a first argument and the function
- * arguments as remaining arguments).
