I do not want that we use re in scripts all over the system. Here are
the reasons :
    - I do not want re text expressions hidden everywhere in the system.
This is the main reason. Many  re expressions should typically be
configurable on a per site basis. I prefer the approach of Document.py.
The expression is defined as a preference and there is an API on
Document.py for using it. Scripts the invoke the class API.
    - consider designing API and class interfaces first. Some class
methods may be re based.
    - if you need to use regular expressions for a quick hack, you can
use external methods. portal_classes makes this very quick and easy.
    - I trust Zope corp on this. So, no re is safer (incl. for the
system stability).
