I know this won't help for syntax highlighting or working within a 
source file that may only be partially parsable. But for an easy way to 
do autocompletion and throwing up 'tooltip' documentation on library 
functions, etc., it should be very powerful.

Generating the data on imports should be very fast, and should not be 
necessary every few moments (only when those imported source files change).

That's far more complex. I'm looking for ways to cover 90% of the 
territory with some simple, straightforward means.
