WG1 - Core

description

This proposal stems from [http://lists.r6rs.org/pipermail/r6rs-discuss/2012-July/006405.html remarks] by Alaric Snell-Pym and Will Clinger on the r6rs public mailing list.  If `eq?` is allowed to return `#f` on two procedures when `eqv?` nevertheless returns `#t`, as is already the case for numbers and characters, then more intelligent implementation-specific procedure comparisons using `eqv?` are possible, while still keeping `eq?` simple enough to inline easily.

Note that this is orthogonal to the question of #460, how `eqv?` works on procedures.  There should be little or no backward-compatibility hit for this change
