What I'd like is for somebody to steal siracusa's RDBO benchmark

it into a tool for benching DBIC vs. other-version-of-DBIC vs. everything

Since you can't have two different versions of DBIC in memory at once, you
can't bench one version vs. another in a single process (and therefore a
single call to cmpthese()). That being the case, you might as well just run
the existing bench.pl script twice with different perl -I ... lib
directories each time:
% perl -I /path/to/DBIC-0.07/lib bench.pl --cmp DBIx::Class ...
% perl -I /path/to/DBIC-0.08/lib bench.pl --cmp DBIx::Class ...
Then compare the results. (I think I'd only need to tweak bench.pl's
treatment of the --cmp flag, which currently always includes
Rose::DB::Object in the list of modules to compare.)

Separate file executions per subject makes more sense in a number of
ways actually, since one tool could have side-effects that may affect
the other, and their order of execution may affect relevant results,
such as if caching is used.
If we want an easy way to put things side by side like combined
executions could give you, then something analagous to a separate
test harness script could be used for that.
