You would probably have better luck shoehorning in such a feature if the
syntax looked like this:
(foo).bar(baz)
foo being a value of some type that has methods, and bar being a method
name. Another possibility is
foo->bar(baz)
I agree with Robert's opinion that it'd be unlikely the project would
accept such a patch into core, but if you're mainly interested in it
for research purposes that needn't deter you.
