OK, I Googled. It seems named constructors is just an idiom not an actual language feature. Pity :-( And the idiom consists of two things: 1) Providing public class (static) factory methods 2) Making the actual constructor(s) protected This has a similar feel to named constructors and is identical to how you would do it in Python (except for the protected bit) or Java. It's not a true constructor function it's just a factory (which calls the true constructors). -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ http://www.amazon.com/author/alan_gauld Follow my photo-blog on Flickr at: http://www.flickr.com/photos/alangauldphotos _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
