And what's the problem with that? 'class modules' I'm using usually
also contain auxiliary subroutines which could also be called 'on
every object' except that this wouldn't be particularly useful: If
you're creating modules supposed to be used by other people and a
significant minority of these use them in ways you originally
considered to be 'useless', that indicates your 'public interface' is
lacking.

Leaving the issue mentioned above aside, you could create a single
'export fail stub' module, put the subroutine into @EXPORT and then do
a

use export_fail_stub;

to import it as method into every module/ class supposed to utilize
it.
