Comment:
I doubt the usefulness of this feature since any top-level function that
is mentioned in the export list of the module won't trigger a warning. It
is confusing to see dead code in a module and so top-level functions that
aren't used should probably just be commented out.
However, this feature does come handy when using records: it often happens
that a field name isn't used in a module, hence triggering a warning.
