How "non-standard" is _defineGetter?

[Ken Tilton]

Total JS noob here, but porting my hairy Common Lisp Cells (dataflow)
package -- long intro on my blog:

http://smuglispweeny.blogspot.com/2008/02/cells-manifesto.html

....so I am getting into some fun stuff straight-away.

I am happy to see _defineGetter_/Setter_ here:

http://developer.mozilla.org/en/docs/Core_JavaScript_1.5_Reference:Global_Objects:Object

Those are crucial to the transparency of my hack, but there it mentions
they are "Non-standard". I would like Cells/js to be portable -- is this
something to be concerned about?

he might have let drop and then sliding into the dugout, which
by the rules allowed the runners to advance one base costing his
pitcher a possible shutout because there was a runner
on third base.

Yup. It's *completely* useless for general purposes. Which (as usual)
means it doesn't work in MS Internet Explorer, which has something like
90% of the user base.

In general, for language level stuff like this, if it isn't mentioned in
ecma-262, you can more or less bet on it not being available in a
significant portion of browsers (and IE doesn't even support all of
it correctly, but AFAICT nothing really significant).

Joost! Long time no. :) Thx, I was having no luck finding a nice solid
JS reference.

And thanks for heading me off form a dead end on the get/set deal.
