At least as far as i'm concerned, i'd like to see actual uses. It's a big 
linecount increase all things considered:

   20 files changed, 2783 insertions(+), 660 deletions(-)

and you say it _wont_ help performance/scalability (this aspect wasnt clear to 
me from previous discussions), so the (yet to be seen) complexity reduction in 
other code ought to be worth it.
