I like this - the problem I see with seperating layout and programming
is that the programmers will just lump all their layout in the program
code. In this way they just have to maintain one page rather than
a DTML page and 'n' PythonMethods/External Methods.

Hmm.... If I could take the following code:

def hello(): print "Hello"
def world(): print "World!"

Could I add it to the current namespace (using existing DTML paradigm)?

<dtml-let common=myMethods> 
    <dtml-comment>Or dtml-width if you prefer</dtml-comment>
    <dtml-var common.hello>
    <dtml-var common.world>
</dtml-let>

ie. a 'library' object will return a map of callable objects.
This would probably have to be seperate to a 'code' object which would
be executed and stdout being its rendered version.
