My reading of the current documentation on casts leaves me with the
impression that D now has only the equivalent of the C++ dynamic_cast.
I'd like this in Phobos:
I'll try again on this.

This seems unreasonably restrictive given that C++ has traditional C-
style cast, dynamic_cast, static_cast, and reinterpret_cast -

I don't understand. Casting a void* to a class bypasses all static type
checks. This is one of those cases where you tell the compiler that you
