This little snippet let's you check what type hides within string before you cast it to other things.

a simpler valid key test:
if ((key)obj) return TYPE_KEY;

also be aware that leading zeros on integers are valid, but will be ignored, and trailling zeros can be reported on valid floats, which may skew your test results for all types using them
