There's unfortunately no real diagnostic I can provide for the error specifically, since the result of the bug is a failed grammar parse. The grammar of my SUPERNOVA project (https://github.com/ShimmerFairy/SUPERNOVA) has been failing since the CURI branch was merged into mainline rakudo, for reasons that are unclear. I can verify that switching to a pre-CURI-merge commit (e.g. 6d9d0f11aba8e2f465c2958a9311d9d4016017ff, the last commit before the fast-forward merge of CURI) will allow the grammar to work again, with no changes to SUPERNOVA, thus it's an issue with rakudo. My attempt to bisect rakudo led to commit ac7b2a5a8381d5f255906437d1980c9c3b77e2a5 (https://github.com/rakudo/rakudo/commit/ac7b2a5a8381d5f255906437d1980c9c3b77e2a5), however as you can see the reason why _this_ commit should break grammar parsing is a complete mystery. (I may try bisecting again sometime to confirm the result.) Like I said, there's absolutely nothing I provide in terms of errors, since the only indicator is just the grammar suddenly failing to match a valid string. It seems to be centered around the "directive" multi token in my grammar, however I don't have any more specific info on the location of the issue.
