I think we back-patch test cases *all the time*. So I think Andres
is quite right to be concerned about making that harder, although I'm
not sure that his estimate of the conversion difficulty is accurate.
I plan to keep a copy of Noah's script and see if applying that to
the patch files alleviates the pain. In a few months we should have
a better idea of whether that's sufficient, or we want to go to the
work of back-patching the renaming.
I doubt that just plopping the new Cluster.pm in alongside the old
file could work --- wouldn't the two modules need to share state
somehow?
Another thing that ought to be on the table is back-patching
549ec201d (Replace Test::More plans with done_testing). Those
test counts are an even huger pain for back-patching than the
renaming, because the count is often different in each branch.
