There is a CPAN module Set::Array . I know it may be a little painful
to learn and CPAN modules for such a small application but in the long
run It helps especially if you are repititively going to use these functions

Hello,
I am very new to Perl, wonder if someone can help me
with this... if I have:
@arr1 = qw (one two three four five);
@arr2 = qw (two four);
How can I remove all elements from @arr2 from @arr1 so
the new array will be @newarr = (one three five)??
Many thanks.
