Re: returning a tied variable

I think you've got no choice but to return a reference to the tied scalar. E.g.

tie $mod,'ModName',{blabla} ;
return \$mod ;

If you're looking for an alternative, one would be to tie a scalar which is passed to the sub (by ref) rather than tying a lexical which is created in the sub. But I'm not suggesting that that's a better way to go.

That's convenient. I was afraid that would simply return a reference to the return value of `tied($mod)->FETCH`, but it does indeed return a reference to the tied variable. Thanks, Perl!

Thnx, So I can conclude that it is not possible to make a copy of a tied variable (or object)!? Luca	[reply]

You didn't say you wanted to make a copy. Of course it's possible. But to help you do that, I think I'd have to see more of the function in question, and also something about the TIE class you're using. We're building the house of the future together.	[reply]
