Hello,
I noticed that js-mode includes the keyword "transient" in its list of
javascript keywords. I can't find a reference anywhere that confirms
this is a real javascript keyword. Is it there in error?
Running js-mode version 9, dated 2009-07-25 in emacs 23.2.1.
Thanks.

It appears the language has changed. According to
http://bclary.com/2004/11/07/#a-7.5.3, "transient" is a future reserved
keyword. However, the official specification at
http://www.ecma-international.org/publications/files/ecma-st/ECMA-262.pdf reserves
a smaller set of keywords. If these keywords do actually work correctly
in modern Javascript implementations, we should remove them from js-mode.

I found that Mozilla warns if you try to use "transient" as a variable
name. So nevermind, it does belong.
