[Zope] SyntaxError, Names starting with "_" are not allowed (__init__).

[Marc O. Sandlus]

Hi

I am trying to execute some example scripts found on zope.org, like this
one:
http://www.zope.org/Members/anthony/tree-coding-tricks
and a modified version here:
http://www.zope.org/Members/rscanon/dtml-tree

So there's this Python script, which I added with the Product List into
Zope:

class _dummy:
    __allow_access_to_unprotected_subobjects__=1
    def __init__(self, name):
        self.name=name

But all I get after clicking into "Save Changes" is:

SyntaxError, Names starting with "_" are not allowed (__init__).

So how can I make theses examples work?

Cheers,
Marc
