Hey Jim, I'm in the midst of writing a paper on ASDF, and I want to properly credit the invention of the '__of__' protocol and its ExtensionClass implementation. I'm in the middle of a section where I'm explaining how __of__ plus wrappers is the world's simplest (and coolest) meta-object protocol for implementing acquisition, inheritance, and method-to-instance binding.
Currently I am referring to it as:
"a simple, yet powerful dynamic binding technique invented by computer scientist Jim Fulton (Digital Creations' Technical Director)"
Is this correct?
If you are looking for a reference I would use some think like: "The __of__ protocol was proposed by Jim Fulton and implemented in the ExtensionClass system [Fulton 96x] ... [Fulton 96x] Fulton, James L., Extension Classes, Python Extension Types Become Classes, http://www.digicool.com/releases/ExtensionClass/ExtensionClass.html, 1996. I happen to agree with you that __of__ an extremely useful protocol that is a natural extension of Python's method mechanism. I feel as though I've been a lone voice in the wilderness advocating it. Are you a member of the types-sig, http://www.python.org/sigs/types-sig/ ? That would be a good place to champion __of__. I think there's been some relevant discussion there, but I've been to busy with Zope to pay attention. :( Jim -- Jim Fulton mailto:jim@digicool.com Technical Director (540) 371-6909 Python Powered!

Thanks for the pointer. It looks like I'm going to have to gird up my brains and dig through the meta-ness, because it looks like these guys are struggling with problems I've been working on with ASDF, and have mostly solved through appropriate kinds of wrappers and appropriately implemented __of__ methods. About the only wrinkle I have left to solve, is that when you access an ASDF class folder directly through a publisher such as ZPublisher, methods currently end up bound to the class and don't know they're not attached to an instance. What you want is to edit the method object itself, and so its 'default behavior' should be to present a management interface when bound directly to the class. Or at the least, it should not merrily try to execute upon the class. :) Perhaps the simplest way to deal with this is going to be to make index_html a ComputedAttribute for method-like objects that are also themselves manage-able. Anyway, never mind all that, I'm gonna go read up on the types-SIG and see if I can further champion the __of__ cause (cause __of__?).
