Re: Know the runtime class

I'm pretty sure that you're describing the pointer aliasing problem, 
which is in general undecidable.  There are a lot of heuristic and 
approximation algorithms that compiler folks use, like Type-Based alias 
analysis, which I think comes in 2 flavors, flow sensitive and 
flow-insensitive.

basically, don't expect to discover that the concrete type of the field 
of type A in C is B.  Expect to discover that the concrete type of A is 
in a set S which happens to contain B.

hopefully, i'm misinterpreting your question and you're really asking 
about something that's solvable.  good luck :)
