Comment (by bonefish):
The cast operator you're looking for is static_cast, not reinterpret_cast.
The unchecked dynamic_casts are really intended, though. In all cases the
actual type of the object is ensured by other means. A mismatch would be a
program error and the immediate crash caused by the NULL pointer would be
desirable (a static_cast to a wrong type wouldn't necessarily cause an
immediate crash). Performance isn't much of a concern in these cases. I
don't know, maybe adding an ASSERT would be cleaner. Or alternatively
dereferencing the original pointer and casting the reference (causing an
exception on type mismatch).
