my @check = grep { chomp $_; $_ } <DATA>;
Map should be used for this not grep. Consider the following.
use warnings; use strict; my @check = grep { chomp $_; $_ } <DATA>; print ">>@check<<" __DATA__ line1 0 line3
The output is:
>>line1 line3<<Grep looks at the value the block returns and if true it returns $_. Map is used to do something to each element and pass along the result from each.
To me it is clearer and simpler to do this:
my @check = <DATA>; chomp @check;
