In the Oberon mailing list, 2018, August, Paul Reed described use of an OutStub module as alternative to "trace = ... IF trace THEN Texts.Write ...". The technique struck me as valuable.
I've added an OutStub to the repository. If there is any objection please reply here or to peter at easthope.ca. If the module is removed, I won't doubt that is justified.
If the module remains for a week or so I'll assume it is acceptable and proceed to import it to a few other modules.
