Re: [Pharo-project] (a = b) => (a hash = b hash)

The golden rule of hashing is (a = b) => (a hash = b hash).  Right?

Look at this:

(1 to: 10) species  --->  Array #(1 2 3 4 5 6 7 8 9 10) species  --->  Array

(1 to: 10) =  #(1 2 3 4 5 6 7 8 9 10)   --->  true

However,

(1 to: 10) hash = #(1 2 3 4 5 6 7 8 9 10) hash  --->  false.

I believe that the last is a bug.
