why brackets & commas in func calls can't be ommited? (maybe it couldbe PEP?)

I have nothing against brackets, and I think Python has used them for
too much time to allow a so big change in its syntax.
But I think in some situations Ruby allows to omit them, solving some
of the "impossibile" problems shown in this thread. This makes Ruby a
bit better than Python to create application-specific mini languages,
that are quite useful in some situations.
