I’m working with a new code base and I ran in a problem which bugs the syntax coloring in Python.
Basically, this line bugs the syntax coloring so that everything after is colorized as a regex :
result2 = something.re_compile(r'''\] ^]* \]''', re.VERBOSE)
Case in point:

The coloration works back if I remove the “r” before the string or if I “close” the brackets :
result2 = something.re_compile('''\] ^]* \]''', re.VERBOSE)
# or
result2 = something.re_compile(r'''\] ^]]* \]''', re.VERBOSE)
Obviously this changes the meaning of the code, but it might help you diagnose the problem.
