That would be fine if dtypes only represented memory layout. However,
in this case, they also represent a difference in interpretation of
str objects in the array() constructor. That is a real difference that
needs to be reflected in __eq__ and __repr__.

enigma that is made terrible by our own mad attempt to interpret it as
though it had an underlying truth."
