I had help only for jsdate.c, from Ken Smith of Netscape (who, per our over-optimistic agreement, cloned java.util.Date — Y2K bugs and all! Gosling…). >> Sorry, not enough time for me to analyze tail position (using an attribute grammar approach: http://wiki.ecmascript.org/doku.php?id=strawman:proper_tail_calls http://wiki.ecmascript.org/doku.php?id=strawman:proper_tail_...). Ten days without much sleep to build JS from scratch, "make it look like Java" (I made it look like C), and smuggle in its saving graces: first class functions (closures came later but were part of the plan), Self-ish prototypes (one per instance, not many as in Self). >> I'll do better in the next life."
