return type from function

It's not as complex as it sounds.

The type identifier for the function is always declared between the function name and the parenthesis ().

Examples:

funcname()             ;returns an integer (lack of an identifier defaults to integer)
funcname%()            ;returns an integer
funcname$()            ;returns a string
funcname#()            ;returns a float
funcname.mytype()      ;returns a mytype type
funcname.bullet_type() ;returns a bullet_type type
funcname.anytype()     ;returns an anytype type
