Thanks and yes the archives are back up. I found a few hits. I see the 
problem. Though, I don't really care if it's a one-to-one match to #succ. I 
would just prefer that my Range#reverse_each method doesn't blow up ;) 
Certainly there must a basic #pred method that makes sense.

Then again how much use does String#succ actually get? And what for? Can 
anyone really give a use case truly dependent on the specific current 
behavior? Would it make more sense if it were simply an ascii "dial", within 
a particular range of characters? And perhaps too that particular range could 
have a redefinable specal global.
