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;. If there were a way to
enforce "only terms that are clearly denote actions can be called
without parentheses," I'd be all for it.

I do not understand why this is damage at all. It's like collateral
fluff, not collateral damage.
Also, is there any case where a function is not a property and do not
denote an action but is still callable without parenthesis? Aside from
bad naming, of course.
