Sometimes, you need to perform an operation over a data structure that includes many different types of data. But, you don’t want to build the operation into the objects themselves, either because you can’t, or because you don’t want to modify every...
In my post yesterday on generic functions, I mentioned that you could use PyProtocols’ new decorators in Python 2.2 and 2.3 as well as 2.4, by using an alternative syntax.What I neglected to mention, however, was that this works only for...
Update as of 2004-11-12: Fixed broken API doc link.I now have a semi-stable generic function API in PyProtocols CVS. This is the same stuff I blogged about on Sunday, but now in a much more usable state, supporting all of Python’s esoteric function...
I just wrote a lengthy post about the interesting virtues of JotSpot and XaraOnline, hit the Preview link, and then my browser’s Back button to go back to the editor.Alas, going “Back” in Blogger’s editor preview doesn’t go back to the editor, it...
