Good.

Ok, that sounds sane, indeed.

I like that idea in general, not sure how to implement it properly, though.
Simplest idea is to make cmake generate a "klocale-{module}.h" file and make 
everyone include that.  But that sounds like a lot of work.

Most solutions have the problem that the string extraction will become very 
difficult since the context (the {module} here) would depend in gcc preprocessor 
or include path setups.

Would be nice to have a solid suggestion for Chusslove :)
