I just tried to modify MochiKit.Base.evalJSON() to use the new
JSON.parse() function when available. This would give us the following
advantages:

1. Speed (but, well... eval() is probably fast enough already)
2. Security

Unfortunately we would also get a nasty regression issue due to the
stricter syntax enforcement in JSON.parse() vs. eval(). It seems that
at least the Firefox parser doesn't accept constructs like these:

  { a: 1 }

since the correct JSON syntax would be:

  { "a": 1 }

Hmm... So what to do? Just skip this altogether? And add a note in the
docs that people should use JSON.parse() themselves if worried about
security or speed?

Any thoughts are welcome.

Cheers,
