You're entirely wrong about that.  HyperTalk and XCMDs are as closely
related as they could possibly be.  I designed XCMDs to be just like
HyperTalk handlers except written in a compiled language.  They have
the same calling interface as HyperTalk handlers, all the same abilites
to send messages and evaluate expressions, and exist in the same
inheritance hierarchy.
