5. Assist++ C++ parser directives
Assist supports simple directives that are passed to it via '//' comments that can be used in cases that original code is confusing:
//$-
Code past this directive will not be passed to parser.
//$+
Code past this directive will be passed to parser (stops //$-).
//$ code
example: //$ void Foo(Bar&)
Code will be passed to parser (adds code that is not part of compiled sources)

//$-
