It is indeed strange behavior, but I think we inherited that from squeak. But it looks like the ANSI standard from which that method emerged is not very specific about it. And other Smalltalkses discussed the behavior as well: http://forum.world.st/New-Dolphin-Goodie-ANSI-substrings-td3362233.html So with both behaviors at hand everybody can be happy, or fight forever over the right definition :P
