I think there are 3 cases:

(3) I don't care. (this arises most frequently in generic code: you're
forced to choose between a field and a function, but you can't have
both).
D1 caters for case (3) very well, but does extremely poorly for (1)
and (2).
@property is perfect for case (1). It also seems reasonable to
disallow property assignment syntax for anything which isn't marked as
@property.
Disallowing removable parentheses for no-parameter functions is the
contentious part.
Good summary. I now wonder, could one overload based on @property?
auto a = container.empty; // check for emptiness
container.empty(); // take the trash out
!
Anyway, I have one more comment about the example:
foreach (line; stdio.byLine) { ... }
vs.
foreach (line; stdio.byLine()) { ... }
Steve said, byLine fetches a range off stdio. In fact it's not - it's an
opApply() based loop.
I was mistaken. byLine does fetch a range.

BTW I love byLine.
