Make this package work with generics

I know in your README you mentioned that this doesn’t work with generic types, i.e.

keys<T>

This functionality would be incredibly useful to me if it worked - and I would love to help contribute if you have any ideas for how to get this to work.

could you go into a bit more detail ? I’m noticing a pretty sweet use that would obviate the need to write factory methods per interface, for example:

export function factoryInterface<T>(template = <Partial<T>>{}): T {
  const keyCollection = keys<T>();
  const data = <Partial<T>>{};

  Object.keys(template)
    .filter(key => keyCollection.includes(<keyof T>key))
    .forEach(key => data[<keyof T>key] = template[<keyof T>key]);

  keyCollection.forEach(key => {
    if (!data.hasOwnProperty(key)) {
      data[key] = undefined
    }
  });

  return data as T;
}

Ok ok I get that this wouldn’t really work, but is there a work around of sorts?
