It sounded like your env is specific to a function? Use a
lightuserdata of the function pointer as the registry key to
store/lookup the env in the registry.

There are many environment tables (a sandbox for each script, which may have many functions) and one globally registered utility function in c.

In the globally registered utility function i need the environment to get at the ID.

I don't have any data to look up the environment with.
