This file should be moved to tests/standalone/TestStatusExpressionsTest.dart so
it is run automatically by the test scripts.

I would move main to the bottom of the file. I believe that is the style used in
the rest of the tests.

[William Hesse, 2011/10/27 15:04:35]

Done.

For all of the ASTs that we generate we should call evaluate in a couple of
environments to test that evaluate works as expected.

Extract this string into a variable and use it in the Expect equals below?
