I sort of figured that. As it is now there's prototype quality written all over it, and I have a hard time getting very thrilled over that since I know from experience that twice as much work, at the very least, remains to make it heavy duty production quality.
In general I don't see much gain from the pike language point of view that it's becoming a bin for half-baked thesis works (not necessarily implying that all the thesis works are that way; I haven't investigated them all in detail). Also, even if the code itself might be fine, its usefulness is imo severely diminished by the fact that the guy who wrote it invariably disappears shortly after the first check-in.
Otoh I don't have much of a problem with them as long as they don't get in the way. This one adds a "facet" declaration to the core language. Can the deficiencies be fixed without changing the current semantics? Or alternatively, should we label it "experimental" and guarantee no compatibility whatsoever?
