Discussed in Rapperswil 2014. A fairly long discussion, with lots of concerns about the motivation.

Straw polls:

Proposal as stated:

SF 1 - WF 1 - N 2 - WA 8 - SA 15

Just the virtual parts, in a new paper:

SF 4 - WF 3 - N 5 - WA 6 - SA 7

Virtual parts and some others:

SF 1 - WF 4 - N 1 - WA 9 - SA 10

We're done for this meeting. We don't actually encourage this proposal to come back, but there are people who'd like improvements for virtual functions.

Closing as NAD, no consensus to adopt.
