There was some discussion a while back about adding some kind of
looping constructs to the Csound syntax, possibly for the jump to
Csound 6. A simple while loop would be great, but from looking at the
archive this might cause problems with backward compatibility for
anyone using w-sigs. I guess for loops are also out of the question. I
know there are some looping opcode already, but I think a simple a 'do
until' would be nice!
