So any object except an Array tests positive for "null" - is that intentional?
isTypeOf({}, "null") → true
Also, if you're going to such lengths, you might as well include the
"function" type in the conditional.
On the whole, I'm not convinced that this function is very useful in
practice. I can't think of many situations where I would consider `false`
and `new Boolean(false)` as having the same "type". They're certainly not
interchangable. The `typeof` operator and `Array.isArray()` are usually all
that's needed.
