There is, however, an edge case that still causes problems: if you return an empty array that you set equal to an array that isn't empty. Here's some code that reproduces it:
In the first block, fn returns an empty array 'array2', and it's then set to 'array1' in the function call. That returns 'unknown return value: array2_0'. It doesn't occur if I put something in array2 within the function, or if I set it to a new array in the function call. I assume this is unintentional.

LAF fn RET_ARRAY array1=array2 END
