I could swear we did once, but maybe it's all in my head.
It's one of the things i was working on before i stopped working on gdb, 
along with the type system rewrite (which is still on a branch, i never 
got around to creating a branch for the former).
No, i have the remnants of a tree where i changed symbol lookup and 
variable evaluation to go through the symbol readers through a high level 
interface to "debug info".
It doesn't compile though (I never finished converting the stabs reader it 
looks like), and it's based on gdb 5.0, so it's probably not worth tarring 
it all up and throwing it somewhere.
