Make explicit size of arrays optional when have explicit initialization

[jchd]

Would it be possible that the declaration of arrays doesn't mandate explicit sizes.

$ar[4] = [ 'I', 'have', 'four', 'elements!']

could then be:
$ar[] = [ 'I', 'have', 'four', 'elements!']

and UBound($ar) would then yield 4. Of course, declaring a larger size than number of initializers wouldn't be an error.

I ask because it's very irritating to have to count things when you code initialy, or after you paste a bunch of elements from elsewhere.

Or: Local $ar = [ 'I', 'have', 'four', 'elements!']

In order to make the initialization assignment efficient, the variable gets created first, then the initialization values are assigned to the array elements directly. In order to allow this syntax,

Local $aArray[] = ['This', 'is', 'a', 'test.']

the initializer would need to be read twice, once to determine its size and a second time to assign the values to the array. I will investigate how to do this in a most practical and efficient manner.

I think I will need the empty brackets after the variable name as a marker that I should be looking for array initializers and that I will need to perform the double scan of the initializer.

Local $aArray = ['Pain', 'in', 'the', 'neck', 'array']

This version will not be happening.

I was suspecting this, so my initial request was suggesting this form. It's also more similar to C and friends and very intuitive.

Do you think you'll be able to generalize to any dimension, as in:

Local $aArray[2][][3] = [ ...

Also since you are at it, can it be made possible to have empty (sub-dimension) initializers:

Local $a2Array[4][3] = [[5], [6, 2, 8], [1], [9, 7]] ;; works fine
Local $a2Array[4][3] = [[5], [6, 2, 8], [], [9, 7]]  ;; current versions chokes at '[]'
Local $a2Array[][]   = [[5], [6, 2, 8], [], [9, 7]]  ;; would be a must

This isn't exactly the same request but it's so close that I don't want to open yet another ticket.

AutoIt does not have a legal undefined value, like perl or some other languages. You need to explicitly declare a value in [], even if "" or 0. Without more detail of what [] is supposed to do, this is not going to happen.

Replying to Nutster:

Sorry but this doesn't sound very consistent with current behavior. E.g. what value is then given to undeclared elements in $aTest[5] = [1] ?
Since in the multi-dimension scenario, after first pass you know which is the "convex enveloppe" (max dimensions) of the hole thing, I hardly see your point.
