*

* @param scriptName name for the script, given to the parsed FunctionNode
* @param startPos start position in source
* @param len length of parse
* @param allowPropertyFunction if true, "get" and "set" are allowed as first tokens of the program, followed by
* a property getter or setter function. This is used when reparsing a function that can potentially be defined as a
* property getter or setter in an object literal.

* @return function node resulting from successful parse
