Thanks for finding the extra uses.
We're excluding some non-integral arguments, but not a consistent set. (That's
similar to a lot of Javascript, so maybe it's ok; I'm just checking that it's
intentional.)
If we want to exclude "strange" input values without breaking "123", I think
the appropriate algorithm is something like:
1. Initialize p to ToPrimitive(V, hint Number).
2. If p is "" or null, throw a TypeError. // Excludes empty arrays.
3. Initialize x to ToNumber(p).
4. If x is NaN, +∞, or −∞, then throw a TypeError.
5. Set x to sign(x) * floor(abs(x)).
6. If x < 0 or x > 2^32 − 1, then throw a TypeError.
7. Return the IDL unsigned long value that represents the same numeric value as
x.
