Re: [Prothon-user] RE: Re: [Prothon-commits] rev 232 - trunk/src

Ben: I was wrong.  Your first implementation was correct.  Just  make the
generator return keys.

dict.items() should be a generator returning tuples of key,value pairs.

I have an idea for making everything that normally returns a list in Python
return a generator in Prothon but have all generators respond to list
functions.  I'll post a new msg about this.
