I don't think having this configurable is a good idea.
Too much code would break as a result and become unusable
for people wanting to use such functionality, so it would
be of limited value.

The above is similar to what we had in Python 2 for enabling
Unicode literals everywhere (the -U option). It was added as
experiment at the time. No one used it due to the massive
breakage it caused in the stdlib.

Why not explicitly code for your use case ?
