Subject: Your word frequency calculator?

Hi! I am studying various texts and code.

Word frequency calculator is one basic tool. I find it an interesting, 
elementary problem to solve.

I found this word frequency analyser by William James:

   freq = Hash.new(0)
   loop {
     data = (STDIN.read(4095) or break) + (STDIN.gets || "")
     for word in data.downcase!.tr!('^a-z',' ').split
         freq[word] += 1
     end
   }

   print freq.to_a.map{|x| sprintf("%7d %s\n",x[1],x[0])}.sort.reverse


Whats yours like? And what about phrase frequency?
