Re: Re: Re: Re: There is a way to LOCK a SCALAR?

Yes you are right!

I found a module to set the readonly flag in the scalar:

  Internals::SetReadOnly(\$foo);
[download]

But the user still can use the same module to unset the flag! ;-P

Soo, using tie or XS to make this will be the same! Maybe I will use tie, since it's pure Perl and I'm already using a lot of tie in the enverioment for other things.

You can always add `sub UNTIE { die "Don't do that!" }` [download] to the class too. :-) duff	[reply] [d/l]

I think my point that in this case education would be better then chains. As in, tell your users/developers why you shouldn't mess with this scalar instead of trying to devise elaborate hacks to not let them.	[reply]
