I guess I mean if there was a module on CPAN that did this I might use it. I'm not presently inclined to include it in the core module, if only because it's obviously something that would be easy to do in a sub-class. > In between the coder the designer is some kind of understanding about > what valid token names are, usually provided by the programmer. > > I think most often this communication is implicit because the programmer > puts the tokens in the document in the first place.

Yes, although I'd wager that the percentage of anonymous subs that have side-effects is much lower than the percentage of methods that have side-effects. I realize that either one could but methods just seem more likely to encourage this abuse. Although, if you want to get to the heart of the matter, code-ref variables were not my idea. I added them in response to a majority of the users declaring their interest.

HTML::Template::Expr exploits code-ref variables to offer function calls, so why not methods too? -sam ------------------------------------------------------- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM.
