I am an avid sbcl and coalton user (and sponsor of both when I can) and never said it was not a great thing; comparing it to Haskell is, outside the theoretical type system roots, just a bit early type system wise.

I agree with you further and you did an excellent promotional comment for Coalton and CL; keep doing that please. I have said many times here before that I did not like my time away from CL and Coalton makes it even better.
