Re: Is map's sub block really being evaluated in list context? wantarray() returns undef..by GrandFather (Cardinal) |

wantarray's documentation says it all really. wantarray is sensitive to the "subroutine or eval" context and is "unspecified in the top level of a file". map isn't a sub or eval so doesn't provide any new context for wantarray.
True laziness is hard work
