You could determine if the file changed since last parsing. That's ok.
My problem was the following:
You have several files open and edit some here and there. The files
depend on each other. So if a file changes code completion must reparse
it - but when? When the file is saved? Or even if it's not saved but was
changed, so reparsed in a (constant) time period.
But I think that's no great problem.

I hope it is. ;-)

No I'm not writing it totally new. That would be a waste of time. But I need
a good concept for type information and currently I'm wondering how
to temporarily modify trees or strings (efficiently).
