Chas Emerick commented on COUCHDB-577:
--------------------------------------

@davisp

No; if you know how to obtain that info, I'd be more than happy to find out=
.  `couchjs -V` only responds with `1.1.3` (the rev of the couchbase build)=
.  Perhaps there's a clever way to get a version indicator from libmozjs, b=
ut I don't know how.

I downloaded the latest spidermonkey js REPL, and it seems to do just fine =
with regex literals.  Surely something so foundational couldn't be broken i=
n the js engine used in Mozilla for years? (=E2=80=A6he asks naively=E2=80=
=A6)
