Perhaps we should revert to a simple set of rules.
1. Empty parens are optional. If there is an ambiguity with the return
value taking (), the () go on the return value.
2. the:
f = g
rewrite to:
f(g)
only happens if f is a function that only has overloads for () and (one
argument). No variadics.
What do you mean by: "overloads for ()"?
That means there must be two overloads of f exactly:
T f();
f(T);
3. Parens are required for calling delegates or function pointers.
4. No more @property.
So:
void delegate () foo ();
foo() // would call the delegate ?
Yes.
a = foo; // fetch the delegate
b = foo(); // fetch and invoke the delegate
