Go figure, besides me feeling stupid and missing that, the documentation doesn't mention that lol thanks stevie... I tried re-inventing the wheel again, but everytime I push it, it still falls flat on it's side...	[reply]

Perfectly acceptable. ++ for using `strict`. Note that the distribution's last release was 1996, and I don't even know if strict was available back then (I'm not in a good position to look up when it was added). I didn't come onto the scene until 2001. `strict` likely wasn't in widespread use back then if it was available, and without strict (subs), barewords are legal.	[reply] [d/l] [select]

"... the documentation doesn't mention that ..." Tie::Dir is over 21 years old (latest release [v1.02]: `26 Apr 1996`). There's quite a few things that its documentation tells you, or omits to tell you, that you should probably change (beyond the bareword issue you've already encountered). You appear to be using strict, which is very good: keep doing that. You should use lexical variables, that aren't shown in the documentation, or `strict` will complain about that. In addition, wherever it shows code like: `new Tie::Dir arg1, ...;` [download] You should change that to: `Tie::Dir::->new(arg1, ...);` [download] See "perlobj: Invoking Class Methods" for a discussion of why you should do this. — Ken	[reply] [d/l] [select]
