assigned to 0.4 milestone as "mode removal" is a big goal
bblum commentedon Aug 3, 2012
will this affect the semantics of passing @ boxes in +-mode? i wrote TLS with this in mind, and am not sure whether or not it will break if changed.
nikomatsakis commentedon Aug 3, 2012
this would not affect the semantics, I don't think.

I think this is possibly-done at this point, but someone should confirm.
nikomatsakis commentedon Mar 29, 2013
This is done.
