This is looks to be the same as [RT#126130](https://rt.perl.org/Ticket/Display.html?id=126130#ticket-history). An old issue, similar to [RT#129275](https://rt.perl.org/Ticket/Display.html?id=129275#ticket-history) with `Numeric`. You're trying to use a `Real` type, but you never defined its things,...

I found another setup that results in `0` characters: changing `{ foo }` to `&foo` in `.then`s: ```perl6 use Test; { my class R1535Log::Async { has $.supplier = Supplier.new; has...

Stresstests added covering OP and a todoed stresstest covering the above snippet: https://github.com/perl6/roast/commit/e70ee88b6171190a8e369cd46b438d05687d9737

> there's no [...] Test::Builder I keep seeing people say that, yet there *is* a [`Test::Builder` in the ecosystem](http://modules.perl6.org/search/?q=Test%3A%3ABuilder). Is that not a good module or do many people simply...

Very similar to [RT#130773](https://rt.perl.org/Ticket/Display.html?id=130773#ticket-history); closing it in favour of this ticket. Fudged tests for original RT preemptively added to S02-types/whatever.t in roast commit https://github.com/perl6/roast/commit/4b2fef409

(for reference, there's an indirect propspec for it already in https://github.com/perl6/roast/commit/ebac29a7e [the `.native-descriptor` tests])

`NumericEnumeration` / `StringyEnumeration` aren't in the spec. Unsure if they are just an implementation detail: https://github.com/rakudo/rakudo/issues/2303

> So it shouldn't be a synonym of +a. Note that doing so would create inconsistency with how `**@foo` slurpy behaves. There's no `**foo` variant for it (don't know why),...
