That was the original idea, but today the situation is that for
all argument-less method calls (and UFCS calls) the parentheses
are optional, but for functions with `@property` parentheses
_mustn't_ be used. This was mainly done to avoid an ambiguity
when the function returns something that is itself callable, but
also is useful to keep APIs stable: If you mark a method as
`@property`, you can replace it by a member variable and existing
code will not break (but needs to be recompiled, of course).
