[Csnd-dev] new parser

for functional style of code writing, we need the type specifier to 
choose the appropriate version of an opcode, like
aSig = oscili:a(.2,200)
versus
kSig = oscili:k(10,1)

is this still necessary in CS7?  or can the new parser "look" at the 
output and see that here is a-rate necessary, but there k-rate?
