Making FFI callbacks call free() automatically when it's collected

Hello list,
Since anonymous FFI callbacks are anchored permanently, and explicitly
call cb:free() every time is pretty troublesome too, is it considered
good to do this?
local cb = ffi.gc(ffi.cast("CALLBACK", function() end), function(self)
self:free() end)
cb()
cb = nil
collectgarbage("collect")
I did print some messages in the callback body and the finalizer body
to verify it's working.
Or is there a better way?
best regards,
Johnson
