Subject Re: JavaScript 1.8 Features in SpiderMonkey (Please?)

procedure is at best, 'interesting'. Also, there's nothing to keep you
from linking couchjs against a newer version of the library. I haven't
groked all of the API breakage but there was a report on the list
awhile back that seemed to indicate that it only involved a minor
