  Various minor fixes for python 3

Switch StdTuple printer from python 2-style "next" to python 3.

Nested iteration changed enough to make the original bitset iteration
code a bit trickier than it needs to be, so unnest.

The end node of a map iterator is sometimes hard to detect in isolation,
don't fail in that case.
