you are not clear in your request but my best guess is you want an
expression in the replacement part of s///. calling that a qq{} is
somewhat misleading as they do have slightly different features. but the
/e option to s/// is what you want. then the replacement is a full
expression and not a string. this is documented in perlop for s///.
