I just got the latest build, Version 1.5.5 (1372), and I noticed that the python language syntax is now somewhat broken for comment characters (#) inside regular expression strings r'some regular expression'.

like:

some_reg_string = r'#'

shows up as illegal / incomplete syntax.

And e.g. all my code following this line:

parentPattern = re.compile(r'^#extends (\w+)\s*$')

becomes:

source.python

meta.function-call.python

meta.function-call.arguments.python
