I was actually thinking about doing this; you beat me to it! =)

Looks good overall. Only three suggestions. One is that the
documentation for const is a little confusing; I would move the
example to the end as I thought that dispatch_types was an actual
function in the module instead of just example usage.

Two, is there a need for a function to get the currently raised
exception (especially without the traceback to prevent accidental
circular loops)? Since that part of the syntax changed it would
probably be good to have a function to call which returns the raised
exception. Don't remember if the 'with' statement cleans up its
variables, but if it does then the traceback object could be exposed
on a context manager w/o leaking.

And lastly, a link back to the PyPI page from the packages.python.org
pages would be good in case the docs end up ranking higher in searches
than the PyPI page.
