The behaviour of such a function is very dependant upon the user's
requirements. Usually none,nil and nil always count as false, and
everything else is true, and hence lua_toboolean() does the job
without the need for an opt or check function. Having none or nil have
some other behaviour would be extremely counter-intuitive in most
cases.

That would be the userdata's environment table -
