Heureka ! The following closure compiles.
v = v_dst.reduce(
(x:Array[Double]{rank==1},
y:Array[Double]{rank==1})
=>ArrayD_add(x as Array[Double]{rail},
y as
Array[Double]{rail&®ion==x.region})
as Array[Double]{rank==1},
v);
But running this code, I am getting the error message below. Presumably my
type casts are too bold. I am currently simplifying the code (which also
should simplify the above closure). Nevertheless, is this supposed to work ?
Should I file a bug for this ?
