So 1.9 does what I would consider to be the _right thing_ :)

So, whats the best way to modify the behaviour of Hash, to fix the bug in 
versions prior to 2004-12-25, and make the behaviour consistent across 1.8 
and 1.9, such that Hash#[], hash#update etc etc work as per 1.9.

I'm sure this must be easy.......Override eql? ?
