Pseudo-equivalent to the `list()` construct but for associative arrays.I don't know if this function can be useful but here it is anyway.

	<?php

	/**
	* Extracts a list of values from an array.
	*
	* @param array $values
	* @param array $vars An array containing keys to be extracted and
	* references to the variables that should be assigned.
	*/
	function array_extract(array $values, array $vars)

Efficient storage of an hollow symetric matrix

	// Let M be a n×n hollow symmetric matrix.
	// M = ⋅ \| M(0, 1) \| M(0, 2) \| … \| M(0, n - 1)
	// ⋅ \| ⋅ \| M(1, 2) \| … \| M(1, n - 1)
	// ⋅ \| ⋅ \| … \| … \| M(n - 2, n - 1)
	//
	// M can be stored as an array A.
	// M(i, j) = A(i * (i - 1) / 2 + j) for j < i.

	// Hollow symmetric matric.

`is.*()` function

	// It is probably best to use `lodash.is*` instead but this is a lightweight alternative :)
