`@batch` with ARM

While experimenting with `@batch` on an M1 Macbook, I noticed that there is no performance improvement when using Julia x86 with Rosetta. With the new Julia 1.8.0-rc3 for macOS ARM, however, the same code runs more than 3x faster with `@batch`.
However, when using `@batch` on some loops, I get this error, while it works perfectly fine on other loops:
```
ERROR: cfunction: closures are not supported on this platform
Stacktrace:

Is that fixable in Polyester.jl? Or is there some workaround?
