I did think of something like that, but didn't get around yet to figuring out how. 

Any idea how much overhead that  method comes with? A priori I'd just need to store a \
boolean.

Talking about overhead, what would be cheaper, storing the result of a dynamic_cast \
in a temp. variable or calling obj->inherits()? (I could peek at the sources and run \
benchmarks but I'm not convinced it'd be worth the time.)

R.
