Just a question about the new PEG parser: will it support lone slash in
raw strings?
In 3.9, the new parser is intended to be a drop-in replacement. That is
still being worked on. For 3.10, user-visible changes can be
considered, but I have not seen any concrete proposals.
the fact that r'\' doesn't work as expected it's a strange exception to
remember.
That said, this seems like a scanner, not a compiler issue.
>>> print(repr(r'\'))
SyntaxError: EOL while scanning string literal
The python syntax highlighter marks all of "r'\')) as part of the
string, ... but
>>> exec(compile("print(repr(r'\'))", '', 'exec'))
''
