A parsing ambiguity arises when the same code can be parsed in
different ways. This case isn't an ambiguity, because it is always
parsed as "z[0]" followed by "()". It's true that until type checking
we don't know whether "z[0]" is an index expression or a function
instantiation. But that is OK. We have similar issues in the
language today for "f(x)", which could be either a function call or a
type conversion.
