Our policy on checking is that we concentrate effort on ensuring that the
host program cannot be crashed from a Lua script, so that when you add Lua
to your application you can rely on its safety. On the other hand, when you
program in C, then you're on your own, as usual (try sending NULL to one of
the string or file functions in the C standard library).

Which users do you mean? Do you have users that program in C? If so, do you
really want to hold their hand?
