There's a module String::Interpolate, but I know of noone who's actually using it.

There's also some trick using eval or related (s///ee), but that could cause more trouble than it solves: it's quite errorprone and, worse, a snakepit of security holes.

It really seems to me like you're trying to create a templating system. There's a very good intro articles on templating systems in Choosing a Templating System. Read that first, and see if you still want to go this route.
