3.2.191 wantarraywantarray This function returns true if the context of the currently executing subroutine is looking for a list value. The function returns false if the context is looking for a scalar. Here's a typical usage, demonstrating an "unsuccessful" return: return wantarray ? () : undef; See also caller. This function should really have been named "wantlist", but we named it back when list contexts were still called array contexts. |
