Maybe something like re""
It should behave exactly like a raw string but would be useful for syntax highlighting and debugging. Perhaps also for type hinting expected regex
input (don't know if this is feasible).

This is unlikely to be implemented. See https://discuss.python.org/t/allow-for-arbitrary-string-prefix-of-strings/19740/12 for related idea discussion.

A nice idea. (Though I'm personally reluctant to make regexps any
"easier" to use than they are already, a discussion for another thread.)

But the IDE/syntax help is cool.

There was discussion of essentially this idea just recently here: https://discuss.python.org/t/allow-for-arbitrary-string-prefix-of-strings/19740 which you will find interesting.

I think it fizzled for 2 main reasons:
- string prefixes current have semantic meaning for the Python
parser/interpreter, while an artbitrary prefix ... doesn't
- "too hard"? to get IDEs to use it?

Of these, I only find the former compelling, and one could argue that
type annotations already form a "has no effect" syntax extension to
Python, so we're already in that playground :-)
