Yes, but you have to do some funky stuff to link it to the typeinfo.   
Compare this to other languages where the compiler generates a very rich  
set of runtime info (e.g. Java).

I think actually, the runtime info generated by the compiler is seldom  
used (except for maybe dynamic casting), and just creates bloat.

I envision in the future, the runtime info generated would be triggered by  
an annotation like @rtti("functions", "fields", "inheritance").  That  
would give us a good hook to selectively generate rtti when it makes sense.
