2.02 Friday 28th December, 2007
	Make use of INT2PTR macro for great justice! (or 64-bit stuff,
	it's hard to tell)

2.01 Thursday 27th December, 2007
	Translated the XS and C into perl using B.  Though the perl looks
	much like C this gives a chance to make it more perlish in the future.
  	There's a tiny bit of XS left to expose some internals to perl space.
	
	Dropped compatibilty for older perls (PadWalker doesn't work 
	there anyway)

0.11 Sunday 9th July, 2006
	Fudge around the segfaults in 5.8.x ithreaded builds by
	not looking up what the package variable is.

0.10 Wednesday 5th July, 2006
	Use strlen rather than playing with SvLEN/SvCUR to determine
	the length of identifiers in the pad.  It's a theoretical
	segfault waiting to happen, but one that isn't tickled by the
	current test suite.  Fixes failures under perl 5.8.8 as
	reported by clkao.

0.09 Sunday 5th October, 2003
	Split Changes out from HISTORY pod section.

0.05 2002-07-25

	rushing.

0.04 2002-07-01
