I must not be reasoning about Event._parse_standard_attr() correctly. I
think it is already looking for _QUOTED positional args, but is working at
it backwards from _KEYWORD_ARGS parsing.
Well, I already wanted to write unit tests for Event. So, I'll try
exercising the class and see what I can see.

While preparing to argue further, I see the mistake I made: SIGNAL command
versus SIGNAL event. I was reading the wrong part of the spec. Please

I've used this on three projects (not counting Stem) and it helps check
that written tests are reaching all the dark crevices of one's code. If
you have questions, I'm happy to help. Once installed, do:
1) coverage run --parallel-mode --branch --omit="test*" ./run_tests.py -u
-i -t RUN_NONE (or some variation)
2) coverage combine
3) coverage html
4) read the nice reports in the htmlcov/ directory
