 * we use `Required` everywhere here because we expect that the methods on plugin objects will

 * `extends (...args: any[]) => any` determines whether the thing we're dealing with is a function.
 * Returning `never` in the `as` clause of the `[key in object]` step deletes that key from the
 * resultant object.
 * on the right-hand side of the mapped type we are forced to use a conditional type a second time,
 * in order to be able to use the `Parameters` utility type on `Required<T>[K]`. This will always
 * be true because of the filtering done by the `[key in object]` clause, but TS requires the duplication.
 *
 * so put together: we iterate over all of the fields in T, deleting ones which are not (potentially
 * optional) functions. For the ones that are, we replace them with their parameters.
 *
 * this returns the type of an object whose keys are the names of the methods of T and whose values
 * are tuples containing the arguments that each method accepts.
