m = n % [mod d] equality mod d (also defined for <>, ==, and !=).
e^`(n) nth formal derivative (groups, polynomials).
e^` simple formal derivative (polynomials only).
`|x| norm, absolute value, distance (rings, int, nat).
x <= y ?= iff C x is less than y, and equal iff C holds (nat, rings).
x <= y :> T, etc cast comparison (rings, all comparison operators).
[rec a1, ..., an] standard shorthand for hidden recursor (see prime.v).
The interpretation of these notations is not defined here, but the
declarations help maintain consistency across the library.
