| descrintro (http://www.python.org/download/releases/2.2.3/descrintro/#__new__) linked from http://www.python.org/doc/newstyle/ still says: "__new__ must return an object. [...] If you return an object of a different class, its __init__ method will be called." But since Revision 26220 - Modified Sat Apr 6 01:05:01 2002 UTC (4 years, 11 months ago) by gvanrossum: "Changed new-style class instantiation so that when C's __new__ method returns something that's not a C instance, its __init__ is not called. [SF bug #537450]" That is, exactly the opposite as said on descrintro. The documentation for __new__ in the Reference manual, section 3.4.1, is correct and says: "If __new__() does not return an instance of cls, then the new instance's __init__() method will not be invoked." Note that the modified behavior was already present on version 2.2.3 (and later) so updating the document currently at /download/releases/2.2.3/ would be fine. | ||

| Note that this is correct in the documentation: http://docs.python.org/ref/customization.html | ||

| Yes, but descrintro is the very first reference under http://www.python.org/doc/newstyle/ "and should be your starting point." (citing that page) Surely there are other documents a bit outdated, but being descrintro in such a prominent place, should have a correct content. | ||

| Sorry, I wasn't suggesting that it shouldn't be corrected. Only that there's already text available to correct it in the Reference. | ||
