# High rank indices (for each i, ..., j)
ref[indices[i, ..., j], ...] = updates[i, ..., j, ...]
This operation outputs ref after the update is done. This makes it easier to chain operations that need to use the reset value.
If values in ref is to be updated more than once, because there are duplicate entries in indices, the order at which the updates happen for each value is undefined.
Requires updates.shape = indices.shape + ref.shape[1:] or updates.shape = [].
