The syntax we ended up with is not really perfect from my point of view,
but I assume that core team knows what they are doing :P

But I still wonder if discussion on standard precedence groups is possible
before Swift 3.
It does not require any implementation: if we settle on something, we will
just need to modify Swift source where precedence groups are located.

> The second review of SE-0077, "Improved operator declarations" ran from
> June 29 ... July 4, 2016. The proposal has been **accepted** with minor
> revisions. This round of feedback focused on naming, both of the attributes
> for precedence groups and the conventions to use for naming the groups
> themselves:
> - The community expressed a strong preference for 'higherThan' and
> 'lowerThan' precedence relationships over the previously-proposed
> 'strongerThan' and 'weakerThan', and the core team **agrees** that these
> are better terms of art. The proposal is accepted with these terms revised.
> - The standard library team reviewed the proposed names for the standard
> precedence groups, and suggests the following minor naming revisions:
> AssignmentPrecedence
> TernaryPrecedence
> DefaultPrecedence
> LogicalDisjunctionPrecedence
> LogicalConjunctionPrecedence
> ComparisonPrecedence
> NilCoalescingPrecedence
> CastingPrecedence
> RangeFormationPrecedence
> AdditionPrecedence
> MultiplicationPrecedence
> BitwiseShiftPrecedence
> establishing a convention of <Noun>Precedence for precedence group names.
> The core team accepts the proposal with these revised standard precedence
> names.
> Thanks Anton for shepherding this proposal through the review process!
