Thanks Chris! I'm happy that the proposal was well-received, and thanks to
Doug for the great improvements for revision 2.

Related, does the acceptance of this proposal imply the removal of the
named methods from FloatingPoint and Arithmetic in favor of static
operators, or do we need a separate proposal for that?

I'll work on a PR to the proposal that covers the changes regarding
classes, and to list the protocols affected by this (FP and Arithmetic
noted above, as well as Equatable and others).
