OK.

Without a caller, it is a bit hard to judge if a separate helper
makes the caller easier to read and understand, or becomes an extra
layer of abstraction that obscures the logic.  Hopefully, having a
more specific function name with "tmp" and "discard" in it makes the
intent at callers more clear than the function that is named after
the detail of the operation.
