Re^2: array with s///g command

[liverpole]

I like brief too ... why not simply:?

my @array2 = map { s/\s+//g; $_ } @array1;

Update  Whoops, now I see ... it's because you'd be changing the original array.  Still, I like the brevity of something like:

my @array2 = map { (my $x = $_) =~ s/\s+//g; $x } @array1;

[GrandFather]

Because that mangles @array1 - $_ is aliased to each element from @array1 and the substitution clobbers the original value
