What bad thing could happen if we make iter() work? If nothing, we should ask ourselves: which is the more intuitive behaviour to expect of iter()? To raise an exception or to return an empty iterator?

I'm +0 for the latter.

-1. I'm a heavy user of iterators on finite and infinite streams and, for me, iter() is an error that I do not want to paper over. The alternate logic implies, e.g ., len() should return 0.

-1 here too. iter() should have an argument just like sum() and len(). regards Steve -- Steve Holden +1 571 484 6266 +1 800 494 3119 Holden Web LLC/Ltd http://www.holdenweb.com Skype: holdenweb http://del.icio.us/steve.holden --------------- Asciimercial ------------------ Get on the web: Blog, lens and tag the Internet Many services currently offer free registration ----------- Thank You for Reading -------------
