Re: Re: Re: aliasing subs

The base sub has to return either $a or $b, $pathname or $filename

Err... no.

sub do_the_match
{
    my $dir = shift;
    my ($path, $name) = ($dir =~ /(.*)\/([^\/]*)$/);
    return ($path, $name);
}

Yes, I'm sorry. I meant must return, by my own specification. I know I can return a list, but I think that would make using the function a bit harder, since I usually only need either the path or the file. That's what complicates the matter; the output depends completely on what name was used to call the function, so if I can't find that out, my implementation is quite useless. It's something that I would like to see implemented in a new version of Perl, though. I think it would be handy in some cases... More clear to read than anonymous subs.	[reply]
