Note that String#<< understands ints as being character codes - so you
do not need the .chr:

irb(main):005:0> str = 100.to_enum(:times).inject("") {|s,| s << (?a +
rand(26))}
=> "uepizlkepyoxxfkefosxxptvcpdiuwyexecngmftnidlyfnhqgmtndbzthhykdjjiyayzwvhatovzbxzqkhclnxwbqbsoxpszwkn"
irb(main):006:0>

I believe in 1.9 you can as well do

str = 100.times.inject("") {|s,| s << (?a + rand(26))}

Kind regards
