We must next ask: Do we care what the 
class/type/race/gender/religion/political-inclination of some_object is?

def foo( some_object )
  # All I care about is...
  if some_object.respond_to? do_some_job
    some_object.do_some_job
  end
end

David Ishmael: It looks like you might still have some grime stuck to 
your clothes from previous languages.  :)  I've been doing Ruby now for 
about 4 years, coming from a Java background, and type declarations like 
you pointed out are one thing I just don't miss, nor found the need for 
in Ruby...
