Awww, thanks! I was kinda hovering around this[1] section and 
didn't quite see the MemberFunctionAttribute list[2]. Is there no 
further description of the behaviour with the inout attribute 
other than for parameters[1] in the spec?
There's an empty 19.10.10 point without content[3] : D. Maybe a 
placeholder?
