Aiui, we discussed this issue in May and Larry explained that this would happen.
Larry doesn't speak up much, and I realized a few months later that it seemed no one had done anything about what he had said. So I filed an issue: https://github.com/Raku/problem-solving/issues/297 Aiui, until we listen to Larry, accept he's right, and fix Rakudo, the results when the topic of a smart match is a Junction will randomly depend on which version of Rakudo you're using. -- love, raiph
