Oh really? Are you sure? I mean PHP I can see, but with Javascript
you can directly access CSS property paths and those properties
values. I haven't tested it, but since Actionscript and Javascript
are kind of from the same family tree so to speak it wouldn't surprise
me if it held true.

Are you saying this from experience or did you just read it somewhere?

Uh, I'm using SwishMax actually, not Flash and I'm exporting as
Flash8, Kiddo. And how would an array change anything...that doesn't
even make sense. The reason for the eval function in Actionscript is
if you need to switch from the object properties path (that's what I
call it, it might have some other name) to the object properties
value.

I wasn't attempting to justify anything. You were the one making the
claim that the eval function had absolutely no use. I was simply
stating that I thought you were full of shit on that point and that
there was a use for it (otherwise why would they have even bothered
making it). I found proof that refutes your claim and now you're all
like, "Oh wait, no wait...it's just in PHP and Javascript that it
doesn't do anything."
