Need Help??

A &&& B # defined-and

You're not the first. Here's the reason why it's a bad idea:

$ perl -ce 'A &&& B'
-e syntax OK

It's not worth breaking backwards compatability for this.

You are right, triple ampersand parses as "boolean and" followed by a "subroutine call sigil". Too bad.	[reply]

The odds of there being code in the wild that does `$a&&&foo()` with no space seem pretty slim to me. It even seems rather unlikely in an obfu. Not that I have personally witnessed p5p be swayed by such arguments before. The odds of "`$a &&& $b`" being non-broken code in the wild seems even slimmer. - tye	[reply] [d/l] [select]
