I think this is from the 80's or 90's where this could save some memory. According to my calculations in Squeak 4.2 with some extra packages loaded it saves at least 36591 bytes (object size + 1 slot in the literal array), which is only 0.79 bytes / method.

Sound package were moved in an external package. The package was broken, I try to fix it but I did not test it, as far as I remember.
