As a convenience, I'm considering exporting the following from the Yesod module: mconcat (from Data.Monoid) <> = mappend (from Data.Monoid) Text (the strict version, from Data.Text) I know there was some talk a while ago of providing a <> operator in base, but I haven't heard anything about it since.
It may not have made it into base yet, but <> is defined in Edward's semigroups package: http://hackage.haskell.org/package/semigroups If you are going to export a <>, make sure it's that one to avoid clashes. Even if you don't export <>, I think it's a good idea to make every Monoid in Yesod a Semigroup instance. And perhaps you'll also find some useful Semigroup instances which aren't Monoids, or shouldn't be Monoids. Thanks, Yitz
