Background links: http://wiki.ecmascript.org/doku.php?id=proposals:proper_tail_calls http://wiki.ecmascript.org/doku.php?id=discussion:proper_tail_calls http://bugs.ecmascript.org/ticket/215 http://bugs.ecmascript.org/ticket/323 Since we aren't done and we are implementing before standardizing, it's impossible to say "for good", but our work is easier as spec- writiers, and implementors of prototype specs have it easier too, if there are fewer requirements operating on the syntactic analysis and runtime semantics. My belief is that if proper tail calls are to make a come-back, it will be through implementors leading the way. As discussed in the linked documents cited above, support by popular implementations on the web would tend to force a de-facto standard. This might not be evident by the time ES4 is standardized, but it could be folded into a successor standard. /be _______________________________________________ Es4-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es4-discuss
