I did not think of that, no: it's just that lua_setupvalue returns the
function's name for that upvalue, so it is easy to create a table
of actually supplied upvalues keyed by their names. Since the
order may be important, the names are keyed by 1,2,...

This is the table format also used by some XML-to-Lua modules.
