Reviewers: jochen, marja,
Message:
I'm not quite done, but this should be close to its final form. I'd be
happy if
you could have a look, now-ish.
I tried hard to make this look pretty and minimally intrusive; please let me
know in case I wasn't successful.
@jochen: For general opinion.
@marja: Since this tramples all over the parser, please have a look.
@both: How should I test this?
Description:
Implement a 'trial parse' step, that will abort pre-parsing excessively
long and trivial functions, so that they can be eagerly compiled after all.
This essentially allows the parser to renege on its earlier decision to
lazy-parse, if additional information suggests it was a bad decision.
