Basically done the chibi impl, there are 6 test failures which appear to be in my own code.

Great! What parts did you implement in C? I hope at least fxcore and rubber-chicken, or did you reimplement from scratch?

I reimplemented from scratch, using (srfi 142) (pending migration to 151),

and `fixnum?' from core chibi. Arithmetic is just (define fx+ +), which is

a builtin opcode (I think a wrapped primitive would be slower, and don't

want to add new opcodes).

Note the test suite refers to `fx=?' etc. instead of `fx='

fx=? etc. is correct (this SRFI is basically R6RS, which uses that convention).

OK, but draft #5 on the site refers to fx=.

The implementation of at least fxlogical-shift-right appears to be missing.

I blew off logical shifts, as I can't see a compelling need for them. If you do have one, let me know.

Not off the top of my head.
