I thought it was the other-way-round -- if they hash equal, they should compare equal? Or is this just for immutables?
In addition, equality should be transitive, so b'A' == 65.0.
I'm not sure what you're getting at... we could certainly have step 2 check for a number instead of an int, and then step 3 could extract the one element, giving an int, and then let that int compare itself with the other number, whether it be int, float, fraction, what-have-you. ~Ethan~

Two values that compare equal must have equal hashes. Having equal hashes does not imply equality. -Fred -- Fred L. Drake, Jr. <fdrake at acm.org> "Give me the luxuries of life and I will willingly do without the necessities." --Frank Lloyd Wright
