— Lua 5.1, 5.2, and 5.3 seemed to have a deficiency in which the stack thread space variable (given as a lua_State*) would die before everything referencing it would be properly dead. This made holding a reference for keep-alive purposes impossible to maintain. Therefore, we retrieve the main thread to keep it alive.
- This is going to start the mark of v4
- pairs() implemented on tables for pairs-like iteration
- .error_handler variable is now hidden from view on protected function! Use set_error_handler/get_error_handler
- packaged_coroutine skeleton, but code is blacked out
- tests rearranged a little bit
- auxiliary keys lookup, search, and storage improved
- overhead of stored tables improved
- usertype registration and un-registration improved
