Dave, Max and I discussed SE-0077 and reviewed the names of precedence
groups.
Here's our recommendation.
In general, we think some names don't read well and have some ambiguities,
for
example, "LogicalAndPrecedence" (looks like a conjunction),
"AdditivePrecedence" ("additive" is an adjective that modifies
"precedence"),
"RangePrecedence" ("range" is not an adjective, stands out).
We think that two directions would be fruitful:
1. If the names of precedence groups will be in the same namespace as
types,
then we recommend pushing the names of precedence groups into a
"namespace",
for example "Precedence.Assignment".
2. If (1) is not workable, we suggest incrementally improving existing
names
to make them more readable and less ambiguous. We think that making the
names less technical by naming the groups after a representative
operation
will be easier for users to understand (instead of "AdditivePrecence" we
are proposing "AdditionPrecedence"). We also think that using an
adjective
before "Precedence" does not read well in many cases
("NilCoalescingPrecedence": precedence that coalesces nils).
