Darn right! I've checked Foldable, Semigroup and Monoid, never thought about the function right above intercalate, thanks! On Mon, Apr 22, 2019 at 2:50 AM Patrick Chilton wrote:

If you want to join a list of Builders with a delimiter, you can use `mconcat (intersperse d xs)` This works for any Monoid.

Hi Cafe,

Just a quick question, the title says it all: how do I intercalate for the Builder? Given what it does, it makes sense that things like `intercalate` should be out of the box, yet I feel the export list of Builder is very limited.
