The latter is certainly tremendously useful for implementing arbitrary
object containers, proxies and other interesting things in C (one downside
is the increased memory usage for all userdata objects).

#define LUA_VERSION_NUM   501
#define LUA_POF           "luaopen_"

Thanks! :-)

And package.loaders is nice, too.


First bug report ... the fix to the tailcall+vararg bug in lvm.c near
OP_TAILCALL is wrong:

 if (L->openupval) luaF_close(L, base);

This should be ci->base, because base may be invalid after luaD_precall.


And a question:

Why have you added parentheses around all function names in all public
header files? This may screw up quite a few code analysis tools
(and maybe some older compilers, too?). In any case, I've never seen
this anywhere else.

Bye,
