Currently, () is optional on all functions, and @property means nothing.

I personally think () should not be optional, and @property should require that () is not present (ie, @property has meaning).

This is annoying:

  alias F = function();

  @property F myProperty() { return f; }

  Then we have this confusing situation:

    myProperty(); // am I calling the property, or am I calling the function the property returns?

This comes up all the time, and it really grates my nerves.

Suggest; remove @property, or make it do what it's supposed to do.
