return EXPR


Returns from a subroutine, eval, or do FILE with the value given in EXPR. Evaluation of EXPR may be in list, scalar, or void context, depending on how the return value will be used, and the context may vary from one execution to the next (see wantarray). If no EXPR is given, returns an empty list in list context, the undefined value in scalar context, and (of course) nothing at all in void context.

(In the absence of an explicit return, a subroutine, eval, or do FILE automatically returns the value of the last expression evaluated.)
