Re: Double interpolation of captured substringsby ihb (Deacon)

I would recommend using another way than interpolation to do what you want, but it can still be a fun exercise.
If you don't want to exercise and really need the functionality, look at String::Interpolate.
To show how to do what you tried to do, for educational purposes:
First generate a string that is double-quoted. This string then becomes what you would use in Perl if you had a change to type it yourself. Since it now is Perl code, use eval to evaluate it i.e. interpolate the variables.
See perltoc if you don't know which perldoc to read!
