Amazing, thanks.

I also just uncovered http://bugs.python.org/issue23316; we'll need to support a patch for that. In fact, bad evaluation order is why I haven't yet gotten down my unification strategy. I wouldn't worry about extra opcodes when using *args or **kwargs, though; what matters is mostly avoiding extra copies. I guess a few `timeit`s will show whether I'm right or totally off-base.

Most of what's needed for the error stuff is already implemented; one just needs to set the top bit flag (currently just 1<<8) to "1 + arg_count_on_stack()", which is a trivial change. I'll push a patch for that after I'm done fiddling with the unification idea.
