For this to be useful, it'd probably be nice to have #193 first, but wanted something like:
Traceback (most recent call last):
File "foo.py", line 146, in trampoline
value = next(value.generator)
File "bar.py", line 51, in _match
eggs()
File "baz.py", line 247, in <lambda>
s = lambda pancakes : 12
File "spam.py", line 165, in next
if new <= len(self.old):
TypeError: object of type 'int' has no len()
to be a little easier to read. When you have a full traceback it can be a little disorienting seeing a wall of red (maybe rightfully so :)
Something like making everything gray, the filenames be bold, and only the first? (last?) call be red would be nice, if not as the default, just to be able to configure.
