 Note that you can't add rules to `DiffRules` directly.
 The reason is `ForwardDiff` works by adding dispatches for the `DiffRules` rules; to do that, it reads the `DiffRules` tables containing all the rules. Doing, say, `DiffRules.@define_diffrule`, adds the rules *after* they've been read by `ForwardDiff`, so you get no dispatches for your custom rule.
 You can also do something to add an additional dispatch of your function for values of type `ForwardDiff.Dual`: `myfunction(::ForwardDiff.Dual)`.
-However, this is redundant and error-prone, while with `ForwardDiffChainRules` you can *re-use* the differentiation code defined in an existing `ChainRulesCore.frule` without having to re-code the diff rules.
