Amen for this proposal. I hope everyone is in favor. A few things
about the current Eiffel libraries are bewildering. The existence of
class HASHABLE is definitely one of them. How on earth is a class
designer supposed to know whether or not someone, someday, is going to
want to use an object of that class as a hash key? Eiffel folks like to
make fun of the prescient programming techniques required for effective
C++ programming. I'm afraid HASHABLE forces us to master some of those
ourselves. As Smalltalk and ObjC programmers know, no harm comes from
class Object having a method hash_code.
Thanks for your time.
Paul Murphy
PS. In case anyone was wondering, I feel the same way about STORABLE.
