 no, it's not recursive.

 ruby just replace the constant with the new class (and you have a message
 "already initialized constant ...")

 For example

svg% cat b.rb
#!/usr/bin/ruby
class A
   def a
      puts "A#a"
   end
end

class A < A
   def a
      puts "A#a1"
      super
   end
end

A.new.a
p A.ancestors
A.ancestors[1].new.a
svg% 

svg% b.rb
./b.rb:8: warning: already initialized constant A
A#a1
A#a
[A, A, Object, Kernel]
A#a
svg%
