private	F * _drop(iterable: Iterable, n: Number): IterableIterator Drops the first `n` values of the input iterable.
private	F * _tail(iterable: Iterable, n: Number): IterableIterator Returns the last `n` values of the input iterable in an array.
private	F * _take(iterable: Iterable, n: Number): IterableIterator Yields the first `n` elements of the input iterable.
private	F * _trunc(iterable: Iterable, n: Number): IterableIterator Yields all elements of the iterable except the last `n` ones.
public	F drop(iterable: Iterable, n: Number): IterableIterator Drops the first `n` values of the input iterable.
public	F * dropwhile(predicate: Function, iterable: Iterable): Iterator Drop elements of the input iterable while the current element satisfies the input predicate.
public	F * slice(iterable: Iterable, start: Number, stop: Number, step: Number): IterableIterator Same as `map( [ i , x ] => x , filter( [ i , x ] => (new Set( range( start , stop , step ) ) ).has( i ) , enumerate( iterable ) ) );`.
