Very important point, I guess we can conclude two things from this
1st in this case it was a pretty bad idea to use symbols, using
strings would have been better
but not overriding instance_methods but by providing a
instance_methods_as_strings method (this is somehow superfluous as we
will see in the second point)
2nd we have to write a completely new class of Ruby programs for
1.8/1.9 and an example will be code like this
   instance_methods.each{ .... unless m.to_s =~ /^__/ }
Cheers
