The function will always return the last statement - you could
return an Array like this:

   HTML::body {
    [ "blahblah",
     HTML::h1 {
       "zomg headers"
     }]
}

-or use 'return' you want to return several arguments, like

def func; return 1,2,3; end
a,b,c=func
=> a=1,b=2,c=3


Best regards,

Axel
