Speedy!

[Andy Armstrong]

trunk is now only 10% slower than T::H 2.64:

prove:  1.000 # (by definition) -- 17.903s
   270:  1.771 # pre speedy branch
   309:  1.955 # pre merge

   534:  2.076 # lots of formatting (phase 2)
   535:  2.031 # grammar streamline
   537:  1.999 # remove _trim() redundancy
   543:  1.673 # conditional utf8

   546:  1.564 # Another small speed hike
   547:  1.515 # More minor speed-ups
   548:  1.537 # Banish accessor bloat
   554:  1.346 # More accessor shaving
trunk:  1.110 # -

The I/O work I did today actually speeded things up in the end.
