Would you accept the following patch:

 --- trollop.rb.orig     2008-10-22 15:24:45.000000000 +0200
+++ trollop.rb  2008-10-22 15:22:40.000000000 +0200

     vals = @p.parse args
     args.clear
     @p.leftovers.each { |l| args << l }
+    class << vals
+      def method_missing(m, *args)
+        self[m]
+      end
+    end
     vals
   rescue CommandlineError => e
     $stderr.puts "Error: #{e.message}."

You then can write opt.num_limbs instead of opt[:num_limbs] , which is not
only two characters less to type, but also more in line with the way I use
OptionParser.

Cheers,
