Obviously the size of the allocated table's header (no idea how Lua
represents this internally, so sorry if I'm mis-using terms) plus the
length of 2 references to another table (I presume all such references
are of a fixed size).

I would be extremely happy to see at least a function to get the
actual size in *bytes* of a given object in 5.2. Perhaps in the debug
library.

Is such a function possible?
