strings and ranges

[charlie.mills]

The following program doesn't execute as I would expect:

#!/usr/bin/ruby

stringy = "X"

1.upto(10) do |i|
puts stringy
stringy.succ!
end

"X".upto("AG") do |ss|
puts ss
end

puts "'AB' > 'AA' = #{'AB' > 'AA'}"
puts "'X' < 'AA' = #{'X' < 'AB'}"

# The code below gets around my problem...

stringy = "X"
while true
puts stringy
stringy.succ!
break if stringy == "AH"
end

# Is there a better way?
