Hello,

Hoping that EWGI will reconvene in Kona, I have prepared a proposal to
allow attributes on expressions, and also proposes the [[discard]]
attribute. It is a draft ... of a draft -- there's still some design
work to be done, possibly with EWG(I) help.

As usual, any early feedback is very much appreciated.
