Aha. Thanks for the link!
It feels like the only difference between a no-arg function that
is @property and one that is not is that the former could be
invoked with optional parentheses and the latter should be
illegal with parentheses.
Whereas an argument taking function marked as @property should
probably allow read or write operations depending on whether or
not it's invoked with an implicit first argument or not:
@property int f(int) { ... }
1.f; // read op
f = 1; // write op
And to make parentheses illegal as well of course.
