I am trying to write a C extension for "NullClass" functiona= lity. I've again arrived at a usecase where I could really use it, so I= 've endeavored to finally code it. However, my C is almost as bad as my= Japanese ;-) I've tried to work out the code just by comparison to how= NilClass is defined, but so far no luck. Here is the repo:=A0https://github.com/rubyw= orks/null. If anyone here could take a look and offer some direction, I= would be very grateful.

Thanks
