It actually looks pretty cool:

% parse_tree_show -u
# ...
^D
s(:class,
  :Bar,
  nil,
  s(:scope,
   s(:defn,
    :def_foo,
    s(:args),
    s(:scope,
     s(:block,
      s(:defn, :foo, s(:args), s(:scope, s(:block, s(:str,  
"foo")))))))))

So the defn foo is just sitting inside. Whenever def_foo gets  
executed, the defn inside gets interpreted, defining the new foo in  
whatever context it is executing in.
