For some reason my dep bot auto merged a failing build of streaming iterables with the v0.1.14 release. Since then I get a "Something strange happened" (logs). I tossed in some console logs and it seems to coming from my batch module which has something that is no longer supported. And the change in 0.1.14 that is throwing seems to be here.
You can test the failure by cloning this commit and running npm build or node bundle-types.mjs.
Happy to debug, but I'm off to enable branch protection.
