I can see several reasons why something like this would be of limited
If you make an error near the top of the file, what do you want it to do;
notify you immediately (thus interrupting your train of thought), or give
up and wait till you type 'cc'? If the second, the advantage is lost
anyway, the first I would find extremely counter-productive.
what about multi-module programs?
Lastly, the speed at which my desktop machine (Sparc SLC - not exactly
state of the art) compiles far exceeds the rate at which I can input
code. Most compile time is taken by large programs that have just had
a small modification, and the compilation could probably not proceed very
far until I finish the mods anyway.

compiler takes (so says Ken Thompson of his Plan 9 C compiler) and that is
quite amenable to incremental precalculation. -John]
