I'm sorry.  I've forgotten who originally suggested this, but the best 
solution I've seen so far is allowing $/ = '', whereby String::each would 
use the invisible space between characters as the boundry for itteration.  
This would require no change in current behavior, and while new Ruby users 
will continue to be bitten by the default String::each behavior, at least 
there'll be a sensible solution to the obviously significant need to 
itterate over characters.  I say "obviously" because there seem to be a 
number of people in this discussion who want that functionality.

In the end, I don't know if this would be faster than using 
String::split(''), but it would probably be more intuitive.
