Should a ref formal accept an array returned by a function
with the default return intent? What if it is a const ref formal and/or
the function's return intent is const ? For example:

proc writeArr(ref X) {  // what if X has a `const ref` intent?
  writeln(X);
}

proc addEm() {    // what if addEm() has a `const` return intent?
  return [1,2];
}

writeArr(addEm());

Today all four combinations of {val,const} return intent * {ref, const ref}
argument intent are accepted. Should they be?
