But "string" comes much closer to having a narrow definition in Perl than "list" does so this would make the problem worse. If I said that tr/a-z/A-Z/ replaced the characters in the first string with the cooresponding characters from the second string, then, to me, I'd be saying that "b" is not changed to "B" since "b" does not appear in the string "a-z".
