[cfe-dev] Getting meta-data into Clang's AST

Ah, I see, thanks for that info.

So Clang at this point supports both types of attributes, I would
guess?  Are there examples using one or the other (ideally the c++0x
standard)?  Where are these objects placed on the AST?

This sounds much better than comments so far.

My project is being paid for by my employer, NVIDIA, so making any of
it public would be a negotiation to say the least.  It really would
depend on how independent I can make it of the PhysX code base.

At this point I am not pursuing that option but the first portion was
completely independent of the code base and if I do it correctly this
portion will be also.  If people are interested I will certainly press
for it once my current set of objectives are met.

I do feel that c++ has needed good introspective capabilities for a
long time and I am carefully walking down that general path.

A foolish consistency is the hobgoblin of little minds - Emerson
