[Python-Dev] Re: Raw strings ending with a backslash

Now that we have a new parser for CPython, can we fix the old gotcha that raw strings cannot end in a backslash?

Its an FAQ and has come up again on the bug tracker.

I do not think that we can allow this, and it is not related to parser. Few years ago I experimented with such change: https://github.com/python/cpython/pull/15217 You can see that it breaks even some stdlib code, and it will definitely break many third-party packages and examples. Technically we can do this, but the benefit is small in comparison with the cost.
