Is it possible to use something like "${1+2}" -> "3"?

I use Emacs, and it's regex replace comes with a handy feature
that \,(any-lisp-form) in the replacement will be substituted
with the value of the expression.  I also want it in Perl, so I
read some manual, and found in s/regex/repl/ the repl is just
qq{repl}.  But I didn't find any notions of this feature.
