Fix a pre typing issue? Can you elaborate? To me it reads like you created an issue with this PR.

@kanongil I like the strong typing, but for practical purposes, you can't use utilities that don't carry the same Refs.

If you run it locally, observe the type test:

        pre: [
            {
                assign: 'some',
                method: ((req) => {

                    return req.app.word;
                }) as Lifecycle.Method<RequestDecorations>
            },
            {
                assign: 'another',
                method: getNum
            }
        ]

In the current state of typings, where one is used as a utility (getNum) and the other is defined in the object. When we define pre[].method() to take a Refs generic, it wants all pres to take the same Refs generic, or else it errors.

If you have other ideas, that'd be great, cause I agree that this is sub-optimal.
