Kotlin/JS target es2015 not usable with Workers

[sgammon]

Kotlin has a new es2015 target for Kotlin/JS. But, when used with KotlinX coroutines, the compiler may generate code which uses eval(...); dynamic code evaluation is not allowed on Workers.

It is not clear yet whether this issue arises from code generated by the compiler, or from KotlinX coroutines, or from somewhere else.

I have filed an issue with the Kotlin team corresponding to this one. I don't expect Cloudflare to open up eval(...), so this is just a tracking issue until more information becomes available.
