Removes first value. 🏃 [:vhs:] 📦 🌔

Similar: push, pop, shift, unshift.

iterable.shift(x);
// x: an iterable
// --> [value, iterator]

const iterable = require('extra-iterable');

var x = [1, 2, 3];
iterable.shift(x);
// [1, Iterable [2, 3]]

var x = [1, 2, 3, 4];
iterable.shift(x);
// [1, Iterable [2, 3, 4]]
