Instead of:
repeat with x = 1 to the number of items in myVar
... could have:
repeat with x in myVar by <delimiter>
Advantages:
- simpler syntax
- consistent with syntax of other new commands in 2.4 like split
Delimiters could be comma|word|return
If myVar was an array you could have key|element as delimiters (specifying whether to
iterate the keys or the values of each element)
Here's the new repeat construct for arrays (from 2.4 beta readme):
>A new modifier to the repeat keyword (for each element) can be used to
>simplify and improve performance of scripts. For example, to loop
>over all the elements in an array variable named "a1", assigning
>variable tElement to each one in turn, use:
>repeat for each element tElement in a1
I think it would be more useful to be able to determine the key as well as it's value.
Instead of the above, why not:
repeat with x in myArray
... where x would be an array containing the key it's value as an array
x[key]
x[value]
This seems simpler and more flexible to me.
