[Python-logic] (no subject)

(Note: When I use the second person pronoun "you" herein, I refer specifically to Nicolas Chauvat rather than to the list as a whole.)
I'll admit that I'm interested in the prospect of logic programing for Python. However, I'm a little confused and doubtful about the status of this "unofficial" SIG. First off, could you please clarify the founding history of the SIG? On the Meta-SIG there was the notice of intention to
create the SIG, one positive reply, and then a message by Nicholas Chauvat stating that SIG creation had been "refused," but no "official" statement of SIG rejection by Guido et al. Was official refusal given in a private
e-mail, or did you withdraw the proposal by yourself? I'm also concerned by the use of the word "refused" - to me (and I may be wrong) the word has connotations that there was active opposition. If there was active opposition, I wonder who was opposed, as I could see no negative comments
on either the Meta-SIG or on c.l.py.
Regardless, I'm also curious as to what the goal of the SIG is. Addition of a new computational paradigm to Python's arsenal is a somewhat major step, and would require favorable winds from the BDFL to avoid the logic-SIG from turning into another lambda. You mentioned in the Logic-SIG creation letter that you had been in contact with Guido. Could you share what he had to say, so people can get a better impression of the framework the SIG works under?
As I see it, there are several levels at which it could operate:
A) Guido loves the concept - do what you have to.
B) Guido likes it - it's implemented, but no new keywords -
new operators (like ?+, as a random example) are OK.
C) Guido likes it - but not at the cost of syntactic change -
internal changes (as in the True/False addition) are OK, though.
D) Guido is fine with it - but only as module in the standard library.
E) Guido doesn't care - it's implemented like Numeric - a quasi-official
package distributed separately from the main distribution.
F) Guido hates it - it is an outcast package, living in the shadows,
begging for food in the street gutters ...
From the SIG description posted on the Meta-SIG mailing list it appears you're leaning toward options D or E:
Logic SIG: Exploring logic and constraint programming with Python
Description: This SIG is for discussing and comparing several
approaches to implement logic and constraint programming
techniques in Python.
Deliverables: A set of modules for people to easily describe and solve
rule-based problems and constraint-based problems in a pythonic way.
Sorry to make this post seem like an interrogation. It's just that I'll bet, if my personal feelings are any indication, that more people would be willing to participate if the uncertainty of an "unofficial SIG" was cleared up, and if they were given a realistic view of what is hoped to be accomplished.
