Re: [Zope] How can I "from future import nested_scopes" in python scripts?

      Hi Shane,

I had hoped that to be true but the following code snippet fails in
Python 2.1 unless I add the "__future__" import and always fails in Zope
2.4beta.  By removing one of the "echoAlpha()" calls from either
"echoBeta()" or "echoDelta()" and the Zope python script works.

---start Zope python script---

def echoAlpha():
	return 'alpha.'

def echoBeta():
	return 'beta.' + echoAlpha()

def echoDelta():
	return 'delta.' + echoAlpha()

print echoAlpha()
print echoBeta()
print echoDelta()
return printed

---end Zope python script---

A similar "pure" python script follows:

---start python 2.1 code---

def checknestedscope():
    def echoAlpha():
            return 'alpha.'

    def echoBeta():
            return 'beta.' + echoAlpha()

    def echoDelta():
            return 'delta.' + echoAlpha()

    print echoAlpha()
    print echoBeta()
    print echoDelta()

checknestedscope()

---end python 2.1 code---

I can get the "pure" python script to work by added the "__future__"
import.

Any ideas?

I'm using Zope2.4 beta with Python 2.1 and I want to use the nest_scope
functionality. However when I add the prerequisite statement:
from __future__ import nested_scopes
at the top of my python script it gives me an "ImportError" and
"unauthorized" message.
You don't have to.  Starting in Zope 2.4.0a1, Nested scopes are always
turned on.
