Hi, 

I just had a look into the source code of the KDEStudio IDE which has code 
completion (which is indeed quite fast!). They bypass the global object and 
#included classes problem by running the gcc preprocessor (gcc -E -save-temps 
or so) and analyzing the restulting files with the ctags program.

One might think this is terribly slow, but it's really fast: a 500kB file 
(which is not too large if you consider all the included headers) is analyzed 
in less than half a second by ctags.

Maybe this could point KDevelop code completion development into a usefull 
direction. If KDevelop would even manage namespaces and code completion 
correct it would be *the* killer app (well, okay it already is ;-).

Just my "2 Pfennige".

Bye, Marcus
