Iterating over a string letter by letter, without having to do 

string.split(//).each {} 

I often find myself using a string as a compact data structure,
essentially a C style array of chars, and need to iterate over the
letters as an analogue to array#each{}. It feels clumsy to add an extra
layer of conversion.
