The PEP contains plenty of examples.  If you're really feeling the need,
add something to the demo directory.

For the most part, the applications need to work themselves out over
time through wikis, individual patch submissions, ASPN recipes,
third-party apps, etc.  

The natural evolution of best practices tends to get thwarted by
prematurely using the standard library to cast a particular solution in
stone.

This doesn't preclude individual patches such as a context manager for
decimal.Context objects.  Each proposal should be considered on its own
merits rather than as a part of an overall effort to ram a bunch of
these into the standard library.    Over time, plenty of these will
sprout-up.
