[Zope3-dev] PythonScript in Zope3?

Zope3 doesn't offer python script as a choice of things you can add to a 
content folder - that's what got me started on this whole thing in the first 
place, finding out what the new equivalent is.

Geez, a "hello world" sample is supposed to be trivial, to get you over 
whatever initial hurdles there are to using a new system.  It's hard to 
contemplate doing more worthwhile things, if you can't do simple stuff first.

Nope, doesn't seem to work, get a NameError: name 'mystuff' is not defined.

Has any of this been actually tried? or is it more of a hypothetical "this is 
how I imagine it probably works?"  or are there more steps?

That's mainly what I'm asking to find out..what are the 17..no 18..18 easy 
steps to getting a 'hello world' example running from whatever replaces 
python scripts :)

(or is the whole thing just not functional yet?)

Yeah, I'd love to see that sort of thing working, changing the default view 
of something, but again it's not obvious what needs to go into the "configure 
a view" form.  I've tried various things, but mostly get:

   AttributeError: GlobalViewService instance has no attribute
    'queryConfigurationsFor'

The big frustration with learning Zope3 right now is constantly reading that 
you "can" do something, but specific detailed reproducible examples of "how" 
to do something aren't easily come by.
