see the attached sample code demonstrating the problem.
basically lib2to3 fails to parse:
dummy(**kwargs if kwargs else dict())
with an error like:
raise ParseError("bad input", type, value, context)
lib2to3.pgen2.parse.ParseError: bad input: type=1, value='if', context=(' ', (3, 21))

This can be circumvented by adding parenthesis: dummy(**(kwargs if kwargs else dict())) |
