erb builds the page piece by piece as a string, then outputs it when 
done processing; anything #printed out along the way comes out first 
because the rest of the page gets printed out all at once at the end. 
You can see the script it builds by calling erb with the -x option. 
(strangely, the generated script doesn't output the string at the end, 
so the script will not run properly...)

I think you are right... it doesn't make sense to me that erb should do 
it this way. If it's going to buffer it to a string, that makes sense; 
but I think it should override Kernel#print and #puts to concatenate to 
the buffer...
