Re^4: Counting the number of items returned by split without using a named array

Well yeah, but aren't you just back to square one?

C:\test>perl -nwle"print $n = +(split)"
Use of implicit split to @_ is deprecated at -e line 1.
Name "main::n" used only once: possible typo at -e line 1.
foo
1
foo bar
2

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?

"Science is about questioning the status quo. Questioning authority".

In the absence of evidence, opinion is indistinguishable from prejudice.

D'Oh! I forgot to -w when I tested it. It's incredible how annoying this little thing can be!!! All in all I would regard the assignment to `@_` and the connected warning as spurious, since split is not called in void context. But... they're there!	[reply] [d/l]
