Re: [Haskell-cafe] strange stack overflow with Data.Map

Should the Map modules have an additional Map.insertWith' that behaves strictly, or might it be the case that you always want strict behavior when using insertWith?

I think so. Once strictness is lost, there's nothing the user of a library could do about it. If a container is too strict however, lazyness can be recovered by wrapping values in an additional data type. So strict variants of updating functions would be a big win, and if two versions of every function are deemed too much of a burden, I'd rather get rid of the lazy version.
