Dependency injection is dynamic scoping in disguise

Scala's implicit parameters and Haskell's typeclass instances are this, correct?

I'm not sure how you'd override the typeclass instance you are going to get easily? (Haskell typically only allows a single instance per type.)

OCaml lets you swap out the equivalent of the typeclass instance. But it's a pain, because there system also means that you always have to specify which instance you want.
