I'd add one thing: people use "assert" way too much in the test suite.

I'll second that.

It's usually much better to just print what you got, and rely on regrtest's output-comparison to complain if what you get isn't what you expected. The primary reason for this is that asserts "vanish" when Python is run using -O, so running regrtest in -O mode simply doesn't test anything caught by an assert.

It can also stop the test script from being used with JPython. A difference that is acceptable (perhaps by necessity) will prevent the remaining test from executing.
