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.

Alternatively, you can ask ghci about the type of "unwrap . > polyToMonoid" and paste that into the type sig. > > regards, > Bartek Ćwikłowski > _______________________________________________ > Haskell-Cafe mailing list > haskell-c...@haskell.orghttp://www.haskell.org/mailman/listinfo/haskell-cafe _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
