We are some collegues writing a book (in French) about Object-Oriented
Languages. We also want to include things like the adresses from where to
purchase languages and systems.

With respect to Objective-C, I have some questions about small details:

1) Is the company selling Objective-C still called PPI ? I wonder if there
weren't a message in news.config or something like that saying that ppi.uucp
had changed to another name, and I wondered whether this was a change in the
company name...

2) In the current version of Objective-C, does the cache mechanism used by the
messenger function only have one triple (selector, class, function) or
several ?

3) In the current version of Objective-C, is there an estimate of the hit
rate in the cache and of the gain in efficiency by using a cache ?

Thanks in advance for any information...
