Hmm... I just had a crazy thought, regarding Andrei's enum bool empty =
false; example. What if in addition to functions as fields (aka
properties) D allowed fields as functions? i.e.
c.foo(5); => c.foo = 5
when method foo doesn't exist.
Sure, you could make fields behave as function. For instance:
int foo;
foo(5); // same as foo = 5;
int bar(foo()); // same as bar = foo;
But then you'll have some problems with delegates and types that define opCall:
void delegate(int) foo;
foo(5); // foo = 5 or a call to the delegate?
foo()(5); // should the delegate be called this way?
and this:
void delegate() foo;
void delegate() bar(foo()); // same as bar = foo, or a call to the
delegate?
You'll need to always write foo()() to call the delegate, which I admit
is more coherent that what we have now with properties, but also
somewhat counterintuitive.
