I'm in the process of adding FFI to pixie. It translates and runs fine (I'm
sure there's still bugs). But the trace is a bit verbose, so I decided I'd
unroll the loop that packs the arguments in the exchange buffer. However
then I get this error:

The line I'm un-commenting is here:
https://github.com/pixie-lang/pixie/blob/master/pixie/vm/libs/ffi.py#L150
>From what I can tell this bug is from the translator trying to do something
with the static methods in CallDescr. Why this is happening, I haven't a
clue.
