Hi Fergal,

Id like to see a slightly different interface:

  is_faster( sub{}, sub{}, "1st is faster");
   

This would be nice but what value should I use for iterations? I suppose -1

Benchmark defaults to -3.  Its hard to argue against keeping (or 
implicitly using) that default.

ie - with optional arguments, and the ability to test for a float-val.
OTOH - this might be too DWEOM? ish
   

DWEOM? 

aka Magic. a term that Tom Christiansen dredged out of old English, (or 
is that Middle Earth)
see perlopentut or http://www.gregorpurdy.com/gregor/wow/000438.html

I don't fancy the float stuff. I think it's doable but if someone
who's not familiar with the module is reading the test script they could
very easily misunderstand it, unless they read the docs very carefully. 
 

or, more like Benchmark::timethese().  this form also allows 3 or more 

I think I'll call that is_fastest().
 

youre way too logical  :-)

FWIW, I started messing about with the TB <=> Benchmark relationship..
with the notion that a few new Benchmark::* classes could represent the
Benchmark results more portably than the various versions of Benchmark do.
(notably the old ones)
   

Benchmark itself could do with refactoring, I though about doing it but then
decided against it because people would have to upgrade to use it or I'd
have to write two versions of T::B.
yeah - thats why I was thinking to slap a few new classes on/into it via TB.
A well-marked living-room invasion as it were.
Also, FWIW, I still want some support for throwing to screen via diag()
   

It dumps the benchmarks to the screen when the test fails. I can stick in a
verbose flag somewhere to make it do that all the time.
 

that sounds good - what Im hoping for is something like these

for 5.00503:
Benchmark: running DD, EzDD, each for at least 3 CPU seconds...
       DD: 3 3.15 0.01 0 0 2399 none @ 759.18/s (n=2399)
     EzDD: 3 3 0.01 0 0 2400 none @ 797.34/s (n=2400)
5.6.2
#   EzDD 10582/3.23 = 3276.161
#     DD  8616/3.17 = 2717.981
5.8.2
#                      Rate           DD         EzDD
#           DD       2011/s           --         -14%
#         EzDD       2335/s          16%           --
my t/speed.t does various unholy version contortions, that would hopefully
be obsoleted by Test::Benchmark
