1. Optional parentheses for normal functions should work shallowly IMO.

Applying

for property function name always applied to its returned value.
#1 is a ratification of current behavior. It allows the combination of
UFCS
and removing redundant ()s.
#2 is a breaking change. If we need it, community consent is required.

I can completely agree with this change. It is perfectly workable to fix
properties without changing optional parens. I just won't use them :-P
I have thought an additional idea.
If we really want a feature to disable optional parentheses for normal
functions, we can add @function attribute to the language spec.
int foo();
@property int bar();
@function int baz(); // new!
int x1 = foo(); // ok
int x2 = foo; // optional parentheses, allowed
int y1 = bar(); // disallowed, calling int is meaningless
int y2 = bar; // ok
int z1 = baz(); // ok
int z2 = baz; // *disallowed* by @function attribute
How about?

Very clever Mr. Hara, I like it a lot! But good luck convincing
