I am experiencing a crash when using parZip inside of an either block.

suspend fun refresh(): Either<Throwable, Unit> = either {
    parZip(
        { refreshA().bind() },
        { refreshB().bind() }
    ) { dataA, dataB ->
        persistData(dataA, dataB).bind()
    }
}

But if one of the suspending functions doesnt return the proper type, the exception is not caught.

The crash happens with an unsafe cast at line 85 of ParZip.kt
f(a as A, b as B)

Is there any way to catch this exception? I feel like I would need to double wrap the Either

Hey @Charlie Christensen,

I am unsure what this is related to. The code you shared should be correct, as it should be safe to use parZip inside of either { }.

Could you share a longer or reproducible example so this could be investigated?
