Hi Bartek, Yes, it compiles, but when I try to use polyToMonoid', it turns out that this function is no longer polyvariadic, unlike the original polyToMonoid . This may be what Luke meant when he wrote "you lose composability". Even with the extra unwrap function I think that this is pretty cool, but I would ideally like to hide the unwrap.

Hello Kevin,

I was attempting to turn this into a small library and wanted to avoid exporting unwrap.
I defined:
polyToMonoid' = unwrap . polyToMonoid
If you disable MonomorphismRestriction this definition typechecks just fine. Alternatively, you can ask ghci about the type of "unwrap . polyToMonoid" and paste that into the type sig.
