In simple cases you might be replacing with the same string every

But you can give it a function that has access to the match object
and can produce whatever replacement string it wants.
You already have a complete programming language at your disposal.
There's no need to invent yet another mini-language for the
replacement string.
There's no need for list comprehensions either, but they're much-used
shorthand.
