This may or may not be considered a bug. But it seems weird to me though, so figured I would bring it to light to see what others think.
It appears that IIF() evaluates data in all blocks, instead of just the block that should be returned.
Example...
$array = '1','2','3'
$test = IIf(1, $array[0], $array[3])
I ran across this issue, trying to golf down some code, so it probably wouldn't be an issue for most uses. But what do you guys think?

But there are legitimate uses for such logic...Let me expound on the example a bit..
If $x is 5 or less it works, but will cause error when above 5, even though the second block would function.
$array = '0','1','2','3','4','5'
$x = 50
$test = IIf($x<6, $array[$x], $array[$x mod 10])

I agree with what you're saying. But in my mind, IIF() should act exactly like an If, Else, Endif. And in currently doesn't.
If this code works without error...
$array = '0','1','2','3','4','5'
$x = 51
If $x < 6
$test = $array[$x]
Else
$test = $array[$x mod 10]
Endif
$array = '0','1','2','3','4','5'
$x = 51
$test = IIf($x < 6, $array[$x], $array[$x mod 10])

(Still remember the thread back then, but the function nature of iif() got erased in my memory somewhen)
