Snap! v12 Beta test (Part 2)

Continuing the discussion from Snap! v12 Beta test (Part 1) - #258 by mark4sisb.

Previous discussions:

Found another quirk: Variadic read-only unevaluated slots (“any” or “number”) don’t appear as read-only.

Additionally, variadic read-only slots don’t zebra colour correctly:

Lastly (and far less importantly), selectors used as defaults in a variadic read-only slot will erroneously be italicized on expansion:

Some problems with string functions when “enforce input types” is enabled, or when inspecting the block definition.

thanks for all of these. They are mostly intentional, because of how we use them in the curriculum work we’re about to release.

I’m going to close this topic now, because I’ll start releasing v12 to production, so we can continue to gradually release all the other works that depend on it over the weekend.

Again thanks to all the beta-testers! I really appreciate all your effort and your reports!
