Yeah, but the runtime behind the virtual machine knows a hell of a lot about
the types. A stream of opcodes doesn't mean anything without the semantics
of the functions the interpreter loop calls to do its work. I thought the
aim of Eric's Parrot idea was that Perl and Python might be able to share a
virtual machine. If both can generate something like today's BINARY_ADD
opcode, the underlying types of both Python and Perl better have the same
semantics.
