There is already the enummapset package.

Isn't it using fromEnum/toEnum under the hood, which might have bigger performance penalty than `coerce`?

Right. However, I am using the package mostly for tasks where I do a lot of 'union' and 'intersection' where there is no need to convert individual elements. I only initialize sets with say, EnumSet.fromList, do a lot of 'union', 'intersection', 'difference', that is, simple bit field operations, and then fetch the results with EnumSet.toAscList.
