Hmm, this is interesting, and I would rather not do this. But actually this solves this example: >>> a = ()
>>> b = ()
>>> a is b

Please do not use this empty tuple directly, and make it a private method on PyContext. I think it is better to call the new_tuple function with an empty vector, so we have one way to create a tuple.

I think this method could be private, or merged into the new_tuple function.

Yeah, not all that big of an optimization, but it seemed dumb to be allocating a new
Rcfor something that's essentially empty.
