Here is my problem with blocks:
#extended
{{block a}}hello{{endblock}} world {{block b}}hello{{endblock}}
#extending
{{block a}}HELLO{{endblock}} WORLD {{block b}}HELLO{{endblock}}
where does WORLD go? It gets lost. Blocks are convenient and not well
defined.
I believe {{def a():}}HELLO{{return}}, the current web2py way, is more
Pythonic and it is better defined.
