I think we might have to accept that they are never going to be comfortable with Python as it's currently constituted, whether or not we suggest that discipline might replace enforcement. Just the same, it still doesn't save them from the consequences of interface miscommunication, as int he case of the Mars lander that crashed because one module provided a (probably strongly-typed) value in meters, and the recipient interpreted it as (probably strongly-typed) feet, cutting the engine out too early. regards Steve -- Steve Holden +1 571 484 6266 +1 800 494 3119 Holden Web LLC http://www.holdenweb.com/ -- http://mail.python.org/mailman/listinfo/python-list
