What's the recommended way of creating a pre-populated two-dimensional array in Scala? I've got the following code:
val map = for {
x <- (1 to size).toList
} yield for {
y <- (1 to size).toList
} yield (x, y)
How do I make an array instead of list? Replacing .toList with .toArray doesn't compile. And is there a more concise or readable way of doing this than the nested for expressions?
