Re: Adding Unique Elements to Array

If i'm reading his request right, here is a way to do that without hashes. I wouldn't recommend this on a large array tho.

push(@array,$foo) unless (grep /$foo/,@array);

`/$foo/` isn't equivalent to `$_ eq $foo`. Personally I use `$_ eq $foo` quite often, as I see no benefit in using `/^\Q$foo\E\z/`. You might want to look at `first` from `List::Util`. `ihb` See perltoc if you don't know which perldoc to read!	[reply] [d/l] [select]
