[PD] Abstraction arguments: tell apart symbols from floats from no argument at all

[Christof Ressi]

unfortunately, this doesn't work. missing arguments will become 0 and therefore can't be differentiated from a float arg with with the same value. I think it's only dollarsyms (e.g. "_$1") where the missing argument doesn't become 0.

I think Pd vanilla really needs a mechanism to retreive the creation arguments as a list. personally I quite like $@.
