Because it denotes an action?
I don't think it is that simple - I see popFront; as an action all the
same as popFront();
Whether you use parentheses or not, it's not a property. The
statement of Andrei is that he doesn't know why it's not a property.
The simple reason is because it's an action.
Now, does popFront; look like an action? Yes. But that is not the
case being disambiguated. It is collateral damage. Because the
compiler doesn't understand English, it can't know whether to disallow
popFront; any more than an ambiguous term like read
...or, as in Andrei's example, 'empty'. In Java you'd write isEmpty(),
or even worse, getEmpty(). In D we now have the option of declaring it
a property, with little chance of people thinking it actually empties
anything.

Great explanation, very convincing!
