Consider the statement type t = returnsArrayType(makeArray()); in the below. How many times should makeArray() be called?

proc returnsArrayType(arg) type {
  return arg.type;
}

proc makeArray() {
  writeln("in makeArray()");
  var A:[1..10] int;
  return A;
}

proc test() {
  type t = returnsArrayType(makeArray());
}
test();

The program prints out

in makeArray()
in makeArray()

I would expect it to only print in makeArray() once.
