Subject: How would you write it  vs Smalltalk

i found a description of Smalltalk in

http://www.engin.umd.umich.edu/CIS/course.des/cis400/smalltalk/freq.html

and then I tried it in Ruby:


h = Hash.new(0)

print "Enter line: "

gets.downcase.each_byte {|b| c = "%c" % b; h[c] += 1 if c =~ /[a-z]/}

p h.sort


C:\rails\depot>ruby count_alpha2.rb
Enter line: This is a test of the line count
[["a", 1], ["c", 1], ["e", 3], ["f", 1], ["h", 2], ["i", 3], ["l", 1],
["n", 2],
 ["o", 2], ["s", 3], ["t", 5], ["u", 1]]

I just wonder how would you write it?  There is no each_char it seems,
unless with ActiveSupport.
