| // XXX: This overload is here because `assertThat` has an overload for `Comparable` types. | ||
| // Unfortunately this still doesn't convince Refaster to match this rule in the context of | ||
| // Comparable types. Figure out why! Note that this also affects the `AssertThatOptional` rule. | ||

Dropped this variant, since in practice it added little.
