/**
 * Strict equality check according to EcmaScript Harmony's `egal`.
 *
 * **From the Harmony wiki:**
 * > An `egal` function simply makes available the internal `SameValue` function
 * > from section 9.12 of the ES5 spec. If two values are egal, then they are not
 * > observably distinguishable.
 *
 * `identical` returns `true` when `===` is `true`, except for `-0` and
 * `+0`, where it returns `false`. Additionally, it returns `true` when
 * `NaN` is compared to itself.
 * @alias module:samsam.identical
 * @param {unknown} obj1 The first value to compare
 * @param {unknown} obj2 The second value to compare
 * @returns {boolean} Returns `true` when the objects are *egal*, `false` otherwise
