Don't we have to?
Wouldn't it be the same if ARRAY and FRED were use-associated symbols, or
if FRED was accessing ARRAY through use-association instead of
host-association?

As far as I know, the scalarizer does this already (in both cases where
pure_function is scalar and non-scalar).
By the way, a temporary is also necessary for
array = Fred(index, other_array)
that is, array need not be as argument to Fred.
