Variables that are collections of `CanonicalVarKind` are sometimes called `var_kinds` and sometimes called `variables`. The former is much better, because `variables` is (a) non-descript, and (b) often used nearby for collections of `I::GenericArg`. I found the inconsistency made the canonicalization code harder to understand. This commit renames various `variables` things as `var_kinds`. |
