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.)

    Forgive a noob, but shouldn't
    push $element, @newArray
    be
    push @newArray, $element
