Re^2: Splitting on tabs then removing extra white space with map

Ah! Thank you! That makes much more sense. I tried every context permutation between map and split I could think of.

Modifying $_ in map is a bad idea.

I though this was one of map's strengths? Am I mistaken?

In what situation would it be a strength? `map` is usually used as `my @new = map { ... } @old;` [download] By changing `$_`, you also change `@old` in non-obvious manner.	[reply] [d/l] [select]
