ruby 1.9.2dev (2009-11-02 trunk 25625) [x86_64-darwin10.0.0]
“Z”…“AA”
[]

“Z”.succではなくてもうちょっと”離れた”ヤツをRangeの終わりとして指定すると"AA"はしっかりと入っています。

surfboard:~$ ruby1.9 -e ‘p (“Z”…“ZA”).include? “Z”.succ’
true

でも半端な”離れ”方ではいけません。

surfboard:~$ ruby1.9 -e ‘p (“Z”…“CA”).include? “Z”.succ’
false

to_aを介しても同様です。

surfboard:~$ ruby1.9 -e ‘p (“Z”…“ZA”).to_a.include? “Z”.succ’
true
surfboard:~$ ruby1.9 -e ‘p (“Z”…“CA”).to_a.include? “Z”.succ’
false
=end
