The issue is that Haml::Helpers, which is included in the scope object,
redefines "puts" as a Haml helper method. In retrospect, this was
probably a stupid thing to name the helper method, and will likely be
changed in the future. For now, though, if you call Kernel.puts
explicitly you should be fine.
