Now I am having problems undestanding what you mean. What would be
"internal Lua code"?

Hehe

I was trying to differentiate between a Lua script and Lua's C code, for example the garbage collector.

 

What I meant was that, typically, this table associating light userdata
with Lua objects is in the registry, and the lookup is done by C code.

This makes perfect sense to me now that you mention the registry.
