Need Help??

in thread regex in list context

I think this explains why I don't like using !~. Ages ago, it "didn't do what I expected" and I learned from this only "don't use !~". Time passed, and I forgot what I was trying to do that didn't work, but I was still avoiding !~ in places it might have worked. I think this just might explain where my superstition came from.

Thank you!

Now that I see the answer I remember discussing this issue and IMHO it makes some sense. What kind of list should be the logical result of a doesn't-match operator? Anyway it breaks the believe in orthogonality and that doubling negations leads to the same results... ... which is indeed not exceptional in perl's "DWIM universe". So the OP should better use `unless` and `=~`. Cheers Rolf	[reply] [d/l] [select]
