	I would like if opcodes (any) could be functions and vice-versa. For functions returning more than one answer we could have a tuple a, b = op(c,d) In general opcodes with one answer could be used as functions, eg. instr 1 out(oscili(p4, p5+ oscili(p6*p5, p5,1),1) endin That would be very nice!

Subject	Re: [Cs-dev] another one for the new parser
	I think it'd be great to just be able to use opcodes as functions. For some reason I thought there were functions in csound that could only be called as functions but not as opcodes, and that the old parser did limit what could be called as a function. It's been a while though since I looked at it and so I'd be happy to be wrong. As for parsing, it seems like it'll be a little tricky. We have the T_OPCODE0 to classify opcodes with zero output args. Maybe we could classify T_OPCODE1 for single arg output opcodes and use that instead of "function" within expr parsing. That may get us close to previous parser behavior, but may also allow multiple-args to functions. We'd have to modify csound_orc_expression.c a bit. To handle what Victor was mentioning with multiple args outputting, it could be tricky. We would have to basically compile expressions to do all the rewriting into a flat opcode list, inserting the synthetic outputs of the opcodes-as-functions into the arg list of the outer expression that holds the opcode-as-function. So something like: aout = sum(someCustomOpcodeWithTwoOutputs(), asig) would become: #a1, #a2 someCustomOpcodeWithTwoOutputs #a3 sum #a1, #a2, asig aout assign #a3 (something like that, with the #a vars as synthetic vars generated by the parser/compiler) The trick is I'm not sure at what point in the parsing we would do validation. Do you think it'd be possible to validate as we went along during the initial parse? Otherwise, reporting errors would be very tricky. I guess also then we could get into trouble with opcodes that have multiple output types.
