I'm thinking this is like bytecode except not smashed flat: you want
to have the bulk of your inner loop's work happen inside a library
call (an opcode, here), because otherwise you lose on overhead. In
Csound this is entangled with the fact that when you have to program
something there's no opcode for, you probably have to set kr=ar too.
The sort of programming I'm particularly interested in is musical DSP,
i.e. writing new opcodes using a high-level language. (If I never do
it in C again it'll be too soon.) I don't imagine there's any way to
have an efficient interpreter for such a language.
