Option 1 has a problem. If you give it a different name in dtml, e.g. 
bar and call it: <dtml-var "bar(counter=5)"> then self is a reference 
to the folder and self.foo doesn't exist. If there is a different method 
'foo' in the folder that other method will be called instead.

This one should work as advertised. (Unless you redefine foo in the 
python module in which case you get what you deserve).
