Hi.

Sorry but the _main_ question of my previous post was...

As far as I'm concerned, I already agreed to a design change, so I 
don't
need to look at what it looks like, so to speak.
However, before I commit anything I want to be able to ensure that 
indeed
_everything_ was translated to the new API, without additions or 
removals.
This I can do if I can run the tests in parallel ("current" and "new"
design); if I apply the diff, it will obviously destroy the "current"
code!
