drop is a transducer that drops or skips over n many items before forwarding every item thereafter. drop-while is a procedure that drops or skips over items until it encounters an item that does not satisfy pred?. n must be a non-negative fixnum and pred? must be a predicate procedure (e.g. symbol?, list?, etc).
