I bet you're right, good call. Now it's a question of how conscious a
design decision that was. If I submit a bug report based on it, they
may mark it "bogus" and say it behaves as expected.
As for my code & why it's structured that way, it's just something I'm
fiddling with to imitate the RSpec syntax. Since that's written in
Ruby, it has some language constructs that don't really exist in PHP.
I'm coming to the conclusion that it won't be possible to directly
imitate RSpec. This is all just preliminary though. I thought I'd
give it a whack. If my code did what you said, subclassing would
indeed be much better.
