Having followed this very interesting thread, I'm still wondering exactly
how much measurable improvement could be achieved. I read an article on
IBM developerWorks (sorry can't remember the URL) which stated that, on
modern VMs, things like object creation aren't the performance bogeys that
they once were. So I'm thinking that before we make a decision about
committing to a change which might break someones app, is there any way by
which we could measure the effects of the proposed change?

I, for one, would be interested to know.
