I agree.  `("A".."AB").to_a` seems inconsistent with ordering and with `("X".."AB").to_a`.

It seems that the behavior of  `("A".."AB").to_a`  is aimed at particular applications.  I am against that:  i think that String objects, as well as Range of String objects, are not supposed to know about traditions of naming of spreadsheet columns.

When I tried to access excel file, I found some inconsistent behavior about range of string. 

ruby-1.9.3-p0 :001 > ("A".."AB").to_a
 => ["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", "AA", "AB"]

This behavior is as what I thought.

ruby-1.9.3-p0 :002 > ("X".."AB").to_a
 => []

However, I tried to access "X" to "AB", and its reaction is inconsistent with above example.

I hope that behavior would be consistent in future release.

Thanks!
