TITLE:
PROBLEM: Debug print() statements cause doctests to fail
Adding debug print(...) statements to code can cause doctests to fail.
This is because both use sys.stdout as the output stream.
POSSIBLE SOLUTION:
Provide and use a special stream for debug output. In other words,
something like
import sys
sys.stddebug = sys.stderr
debug = lambda *argv, **kwargs: print(*argv, file=sys.stddebug, flush=True,
**kwargs)
Note: Need to use current value of sys.stddebug, so can't use functools.partial.

Or write your debug output to stderr?
