That's not what was asked. Adam's example was pretty clear.

Eh? I wasn't the one asking the original question, but the one providing the fragment.

You're right about lua_ref/unref et al [including the registry], though.

Oh yeah, these functions have been moved/renamed, since Lua 5... I wish they'd be put back into the "official" [read: documented in the ref manual] part of the Lua API.

It looks like the technique is now referred to as a "trick". I think that's bad: it's far too essential. Now it leaves newbies clueless. Ah well.
