I can imagine binding C APIs by creating Lua objects that hold a
reference to the C object. If the library lets you allocate the memory
yourself, then garbage collection can be handled for you. Otherwise
just the pointer cdata will be gced, so you must write your own __gc
metamethod to call the library's free function - but this isn't
supported on tables. Is there a better way than creating a newproxy
for each object and giving it a __gc metamethod that makes the
appropriate free call?
