I like to manipulate data structures. Sometimes the final out put of that manipulation is a string. So I find myself using the pattern of map + join and its starting to feel like the map + flatten of old. Sadly, ruby does not have an answer for this yet, so this is what I've written in the mean time.

def map_join(arr, sep, &block)
 arr.map(&block).join(sep)
end

map_join([1, 2, 3, 4, 5], '-') { |x| x ** 2 } #=> '1-4-9-16-25'
