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

[c4onastick]

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;

By changing $_, you *also* change @old in non-obvious manner.
