Jaro: PTAL.

Michael: FYI. optparse :-)

lgtm.

Would it make sense to generate global object reference?

File tools/generate-runtime-tests.py (right):

tools/generate-runtime-tests.py:255: value = random.lognormvariate(0, 15)
We might also want to add smallest/largest positive/negative representable
numbers.

Would it make sense to generate number strings? (Perhaps parenthesized versions
of _Number.)

Thanks for the review and the comments. I've added stuff as suggested.

Maybe unify this with commands.py in the future?
