I completely agree.  In GCC, the current IMA stuff is sort-of halfway 
in-between.  The representation we use is basically at the source level, 
but, as Geoff mentions, we don't quite fully squish everything together 
into one translation unit.  So, it's pretty similar to C, but if there 
were a source language for this representation, it would also have some 
kind of "module" construct.

I know! :-) I used to write tools that found the mismatches, and they 
are pretty common.
