That would have been me. I think I was arguing simply from the
implementation complexity standpoint (my comment to Dmitry about the amount
of code needed to implement parameter passing would be a lot worse with this
capability). I think your argument was that such things should just be
implemented as records, but that leads to the explosion of possibilities
(now every array might be implemented in a number of new ways on top of the
old ways). I'm not sure I'd make that argument again. (I know I wouldn't be
against 'in out' parameters in functions again. The use of access types to
replace them is disgusting.)
