in reply to Yet Another Variable Expansion Problem

Well, if you would change the match to something like the following and have him stick all the variables in a namespace other than main:: you'd be better off than you are. The key trick is requiring a real word character after the '$'. $template =~ s/\[\$([a-zA-Z][\w\[\]\{\}'"]*)\]/'$Q::'.$1/eeg;

Basically, lop off the '$' too, make sure the first character is really a letter (and that one exists, yours allows [$] which isn't real good), and stuff that string onto a variable in another namespace.

If you are sure that every variable is a scalar you might just do /\[\$([a-zA-Z]+)\]/$hash{$1}/eg; as well.

And yes, I'm ashamed that I'm on the Template-Toolkit list and still helping you do this the wrong way. =) =)
