Hmm.. the old code will break only _if_ the new type() is there _and_ some userdata implements the __typeof metamethod.

I think this makes the chances rather slim, also the calling code would implicitly expect Lua never-ever to get any more types than it now has, which is bad presumption anyhow.

Just because a facility has consequences that may be problematical is no
reason to utterly dismiss the facility.

     Luiz is talking about all the old code that would break with this
new type function. Unfortunately people can't see the future yet, so
as to avoid burning themselves.
