```Thinking on it... (Number|Object|String) .strict(Equal|Greater|Less...)
Methods (a, b) might be better...  If either value isn't a match for the
bound type, it's a false, even if both sides are equal...

Ex,.

Number.strictEqual(null, null)  false

Object.strictEqual(1, 1)  false
...

If you're doing a strict compare, one can presume you should know what
you're comparing.
