+1 from me.  As an experience report, I just ported the diagrams
package to mtl-2.  As a matter of fact it did require some changes,
because one place in the code explicitly used the Cont constructor
which had to be changed to ContT (and some Identity wrapping and
unwrapping added).  But it wasn't a big deal and it works fine now.
