in reply to Re: Removing empty string elements from an Array
in thread Removing empty string elements from an Array

Aside from the issue of readability, which is obviously subjective, this solution will drop any occurences of '0' from the array. A more explicit check is necessary, as in the earlier grep solutions:
my @newArray; foreach my $element ( @array ) { push $element, @newArray if defined $element and $element ne ''; }
(Personally, I also prefer grep to solve this problem.)
