One would imagine that if someone overrode the result of type, then
they'd *want* that to fail.
Asko: As with most limitations on metamethods, I'd advise patching
it in yourself. I've had to do this because I wanted to do real
metaprogramming, and after a few tweaks, it works great. I've made
objects that appear to be true numbers to any Lua code, but are in
fact tables containing proxy objects. I've not profiled things, but
I think it's only slightly slower than stock Lua. It's an easy
price to pay for flexibility, though.
