Request: `Slice` or `Rest`

[matthias-ccri]

Use case: writing a facade for a function, that supplies the first function parameter:

import { getVehicleFeatures } from './vehicle-utils';

declare const vehicle;

function getFeatures (...args: Slice<1, Parameters<typeof getVehicleFeatures>) {
    return getVehicleFeatures(vehicle, ...args);
}

So the getFeatures function has all of the parameters of getVehicleFeatures except for the first, which is the vehicle itself. This is a form of currying. It allows getFeatures to reference the parameter array type of getVehicleFeatures and get a type with all the params except the first.

Alternate suggestions welcome :slightly_smiling_face:
