Review comment:
@vinceab it would be great to better understand your pain points. i'm
still concerned about checking in untestable code to python/, particularly in
target.py. but perhaps if we have a more complete example it would help us to
understand the shortcomings with our existing docs. in particular, so far i'm
wondering whether we should have some type of wiki or page where implementers
on a particular device could provide snippets such as these and discuss any
wrinkles or problems they had.
