Thanks for your patch!


Some places from prevous review are still not fixed for some reasons.


Please be careful with our Lua style guide I ponted some obvious violations.

Also it would be great to analyze module functions with our memprof. I 
think there are some

places that could be optimized.

Do we have any benchmarks that shows that FFI is faster than Lua C API?

Or it's just easy way to implement such module.

You've aleady declared cdt as ffi.C. There is a redefinition here. Is it 
really needed.

I don't see anybody use "native" for ffi.C. There are two ways - 
"builtin" and "C".

I suppose to choose one of them.

To be honest it's not completely clear that such value means until

I visited 
https://github.com/chansen/c-dt/blob/21b8cd1fcb984386b7d4552c16fdd03fafab2b6a/dt_config.h#L50.

I think some comment is needed here.

As in the previous review it will fail on attempt to compare with not 
datetime value.

Here you recreate handlers for each iteration of the loop. I think it 
should be reworked.

Currenlty it's quite slow I think even if-elseif-else branches will work 
faster without

creating redundant GC objects.
