Yeah - the shim stuff is now all in the .XS file mentioned in the 
original mail. 

For what it's worth you can see the code I'm working on here

(which, caveat, still needs checking over for correctness, 
non-leakyness and general stinky code)

The relevant bits can be seen in Fast.xs and the options(..) method, as 
used in new(..) but basically it's a XS method with variable args that 
loops through the remained of the stack, 2 at a time, and then added the 
variables to a struct and passes that struct into the C.
