I don't think there are any rules as such. Casting in D is not well specified. Between classes you'll probably get a dynamic cast which happens at run time and a dynamic cast can return a null reference, so you'll get a crash if you don't guard against it. You can force a reinterpret cast by casting to void* and then casting again, but you have to be careful doing that as you are deliberately subverting type checking. - -- My enormous talent is exceeded only by my outrageous laziness. http://www.ssTk.co.uk -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iD8DBQFLkqbKT9LetA9XoXwRAiTtAJ9STEAd+nQxf9URIV+X9HTwLr6TJACfaGoi fTrzOMyeQNbH95gsj+4sNTU= =eYEH -----END PGP SIGNATURE-----
