In this case, a simpler solution is to use a single table with an __index
metamethod only. Writing to fields in the table will not affect the C
values. Absent fields will be read from C via the __index metamethod.
This metamethod can also save the values in the table, so that it will
act as a cache for C values (which may or may not be desirable).
