something I use a lot:
   a, b, c, d = ARGV
   b = b.to_i

or:
   print "What's your favorite number? "
   if (num = gets): num = num.to_i end

or:
   print "Enter a date: "
   if (date = gets): date = Date.parse date

I find it incredibly useful that you can assign differently typed data 
to the same variable throughout it's lifetime. just reusing a variable? 
no, that's bad programming. But replacing it's data with the same data, 
just in a different form? I think that's okay, myself.

just my 2�
