Return type is int.

[Lasse Reichstein Nielsen, 2013/04/11 07:54:04]

Why are the iterables untyped? I was assuming typed arrays would work with both
int and double elements.
I can see that other elements are typed as int, but in general, the types are
absent from TypedData.

If they work only on ints and nums then they should probably be typed "num".
The joy of non-written types...
