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?
@function seems like an extra complication. Ambiguity between
setter and getter for @properties when UFCS come into play are
not solved. Functional style is impaired as you can't pass
regular function around, just @function . You'll still find trap
in generic code around the behavior of regular functions.
