in thread The Mother Tongue

It's hardly broken; as with any code, one must understand how and why it works, what are its limitations, and not go about applying it blindly to every situation (eg. a deep compare of nested data structures). In any case, the simple-minded (shallow) approach is usually the one that is wanted for this task, especially when writing in OO-style.

As a further aside, my idiom is usually:
  
my %uniq;
undef @uniq{@arr};
@arr = keys %uniq;

    Or you could do: 
    sub uniq
{
    my %u;
    @u{@_} = @_;
    return values %u;
}

@a = uniq @a;
