I didn't say you couldn't build regexps dynamically. I said the quantifier can't be variable. Perl regular expressions don't even have variables, so you couldn't possibly have shown one being used. You can't have a quantifier until you have a regexp, and you don't have a regexp until you interpolate anything that needs to be interpolated. What's the quantifier in the following?
Are you saying it's different in this one?
What about this one?
In all cases, the quantifier is {2}. No variables is involved. Sure, the regexp is produced from a variable, but that has nothing to do with the quantifier. Update: Clarified. In reply to Re^3: Regex fun
