Void context

As to how Perl can be improved. I agree with tye, map and grep should generate a warning in void context. I'd leave out the foreach recommendation except under diagnostics.

In the same vein, Perl should have a wantvoid or wantbool operator so that the general case can be handled.

Perl should have a wantvoid Well, wantarray already returns `undef` in a void context. Has for a very long time. -- Randal L. Schwartz, Perl hacker Be sure to read my standard disclaimer if this is a reply.	[reply]

Great. Thanks. Guess I'm going have to make an effort to catch up on the parts of Perl I "know". And guts was getting so tempting. rir -- only about seven years behind the times	[reply]
