compile-time variables?

I see.  Well rule number 1 of CTFE is "no side effects".  So I think 
that pretty much prevents this from working at compile time, since 
storing a state somewhere is definitely a persistent side effect.

Are these IDs all in one file?  If not, then in any event you're going 
to run into trouble making the IDs unique across files with a 
compile-time technique.
