I don't see how continuation-passing and bytecode have anything
to do with each other.

I haven't seen any so far, although I haven't really looked
for these things.

I get the impression that speed isn't a major design goal in
this implementation of Ruby, at least not as much as it is
in CPython. All of Ruby's built-in operations go through a
method lookup, for example, even adding two integers.
