Fair enough, I haven't followed this thread too closely and didn't consider
the "in" operator being used. Even then I find it unlikely that confusing
re'...' with r'...' and not noticing would turn out to be an issue.

That being said, I'm also -1 on this, especially now after your point on
"e-string". Adding these re-strings would straight out prevent e-string
from ever being implemented.
