Description (last modified by Tim Graham)

There are some places in the test suite that follow this pattern:

try:
   CharField.register_lookup(Length)
   # some test code
finally:
   CharField._unregister_lookup(Length)

It'd be better to use a context manager (addCleanup() was originally proposed) to handle this stuff.

Has patch: set

The current patch is using a context manager instead of the try/finally method.
Mads, is that something you are comfortable with, or do you still see some benefit with addCleanup?

Patch looks good to me, unless there's some reason to prefer addCleanup().

Using context managers should be fine as well.
