I don't think that it is a good idea for numpy to add such multi-dispatching, it is not its job. There are a lot of ways to do it, and besides it would be very cumbersome to have something specific to Numpy (that is only for Numpy's types), because when ctypes will be used with something else than Numpy, it would be a nightmare. The only thing you have to do to have your own dispatcher is to wrap the C functions in a Python function that will call the good function. It is very straightforward, so you might think that this solution could be integarted into Numpy but : - for such simple code, it is not very useful, a wiki entry can do better - if you have a double dispatch to do, you would have to implement it yourself, so you would have to check the code (or the wiki entry) and you would send a mail to include a double dispatcher to Numpy - etc for a triple dispatcher, four Matthieu -- French PhD student Website : http://matthieu-brucher.developpez.com/ Blogs : http://matt.eifelle.com and http://blog.developpez.com/?blog=92 LinkedIn : http://www.linkedin.com/in/matthieubrucher
