trial is also an extension of the stdlib unittest module (less and less
over time as more and more stdlib unittest changes break it).  Incremental
improvements with backwards compatibility are a great thing.  I very
strongly encourage that course of action.  It has already happened a number
of times in this thread that some proposed functionality already exists in
some third-party unittest extension and could easily be moved into the
stdlib unittest module.  That's a good thing: it shows that the functionality
is actually valuable and it makes it easy to include, since it's already
implemented.

For what it's worth, trial is MIT licensed; anyone should feel free to grab
any part of it they like for any purpose.
