Hi,

in following example the @property method needs the ()
otherwise compiler error  for row 24 is thrown.
I cannot judge, whether the compiler behaves correct or not.

Kind regards
André

alias fnError = void delegate(string s);

interface IfSession
{
	@property fnError addError();
}

class Session: IfSession
{
	private fnError _addError;
	
	@property fnError addError()
	{
		return _addError;
	}
}

void main()
{
	auto session = new Session();
	session._addError = delegate(s){};
	
	session.addError()("test"); // Works
	session.addError("test"); // Does not work
}

a known thing. not sure if this is a known *bug* (seems that almost
nobody cares). compiler is obviously wrong here (and i believe that
it's wrong to accept `()` for properties at all), but i don't know if
this will ever be fixed.

There's hope that this will get fixed in the near future:

Thanks a lot for the info.

Kind regards
