WRT not needing an extension I guess this is part of a general pattern where you don't need extensions to use code that uses extensions. In this case though it seems a bit odd in that using the code that uses extensions also requires previously illegal syntax. But as long as it's intentional it's fine by me.
But is the bit where the calling module needs FlexibleConstraints also intentional?
It looks like it is. According to [1], the context must have the form `C a` unless FlexibleContexts is enabled. [1]: https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/other-type-e...
