Please see my variadic_macro_data library in the sandbox. I have already addressed the problem of uniting variadic macros with Boost PP there as well as providing the support for tuples which you suggest in your opening paragraph above.
So why hasn't there even been talk to get this reviewed or integrated into Boost.PP?
I have no idea. I do not think it is up to a library developer to constantly endeavor to promote his work, other than to do as excellent a development as he can. Dave Abrahams noticed it but no one else reacted to my original announcement. I too would love to see this library added to Boost but I do not think it can be added directly into Boost PP but rather exist as a separate Boost library. Paul Mensonides, the creator of Boost PP, in e-mails to me expressed the fact that he really did not want to add anything else directly into Boost PP since it was a fragile enough implementation given that it has to workaround bugs in many C++ implementations of the preprocessor, especially VC++. He also is working now on his own preprocessor library which needs a far more compliant C++ preprocessor than most compilers currently have. So I believe it would be best to add my library as a separate library to Boost.
Are you referring to Chaos/Order [1]?
Yes, although I can never find any files for it. But as far as I understood from Paul you could not use it with somewhat broken preprocessors, like the one in VC++, so its usage must be limited to highly compliant preprocessors like Boost's own Wave and perhaps a few others. I also ran into VC++ preprocessor problems with my variadic_macro_data library and had to find workarounds for them, largely by using some of Boost PP constructs as intermediary operations.

Questions, comments, suggestions etc. are all welcome regarding my library.
I think macro composition and argument binding like that supported in Chaos/Order (forgive me, I'm not really sure what the difference is) would be great.
Please be specific. Remember that the focus of my library was strictly to be able to use variadic macros easily along with Boost PP. I was not trying to do much more than that because I wanted to merely support what already exists in Boost PP with the addition of using variadic macros easily with it. I do not mind trying for more but I want to stay within the confines of what can be done with variadic macros to work with the current Boost PP. Also if Chaos/Order can do these things you may want it might be a good bet that they can not be done with the many of the compilers which Boost supports.
I remember another individual posting a link to a preprocessor library in the past on the developer's mailing list that did something similar [2].
On this site I see no files which can be accessed. Perhaps there is a way to access these files via cvs but I do not see instructions for doing so.

I do not know who this is and surely, whoever it is, he needs to put his work somewhere ( sandbox, vault ) where it can be found by others. Thanks for your interest in my library.
