Well, I didn't falsify my results :-) It really did do this:

>> ("!".."~").to_a
=> ["!", "\"", "#", "$", "%", "&", "'", "(", ")", "*", "+", ",", "-",
".", "/", "0", "1", "2", "3", "4", "5", "6", "7", "8", "9", ":", ";",
"<", "=", ">", "?", "@", "A", "B", "C", "D", "E", "F", "G", "H", "I",
"J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W",
"X", "Y", "Z", "[", "\\", "]", "^", "_", "`", "a", "b", "c", "d", "e",
"f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s",
"t", "u", "v", "w", "x", "y", "z", "{", "|", "}", "~"]

as I stated. I think that means it *has* changed. This is "ruby 1.9.0
(2008-04-30 revision 16244) [i686-darwin9.2.2]"
