[PD] Number of Creation Arguments of an Abstraction

[B. Bogart]

Maybe there should be an undefined type in PD...

a "undef" or something so that you can test arguments against it. (or
another special $ variable in an abstraction would be the arg count,
like argv/argc stuff:

[float $$] <- number of args to this abstraction

[float $1] <- first arg

[float $0] <- unique ID for abstraction

I guess $-1 could also work, but looks really junky.

Actually I would prefer something like [float $argc] [float $unique]

but thats me and words...

.b.
