@deriving(accessors) generates curried functions in uncurried mode

[DZakh]

@deriving(accessors)
  type msg =
    | ShowToast(string, toast)
    | EnterToast(string)
    | ExitToast(string)
    | RemoveToast(string)

This way it's not possible to pass a showToast to a function callback. I'm personally not a fun of @deriving(accessors), so I'll remove the usage of it, but still I'd like to let you know about the problem.
