I think the re module is a good example for arguing that DTML and
Python Methods should have different criteria for deciding what
modules are available (and separate permissions for users, if they
don't already).

Somehow, the idea of mixing regexps and DTML gives me chills, but I
agree that it is a perfectly reasonable tool to want to use in Python Methods.
This relates more the crusade to depricate DTML programming as opposed 
to DTML report writing than it does to security concerns.
