What do you mean by that?

Reading can be somewhat simplified:
# untested
IO.foreach("testfile.txt") do |line|
if /^\s*(w+)\s*:\s*\b(.*)$/ =~ line
dict[$1] = $2
end
end
> dict.sort
This sort is useless as it will not sort the Hash but return an ordered
array of arrays. You're only wasting CPU cycles here.
