Hmm, it's pretty general practice in all the other embedded languages 
that use the <% %> style coding to be able to also print directly in the 
language, ie sometimes it makes more sense.  Is there a particular 
reason the code generation places the puts before hand?  I mean from my 
reading of the way erb works it shouldn't be doing that?  Anyone have an 
explanation to this behavior?
