What FP can learn from Smalltalk

I love functional programming, especially with types, my code is less buggy, easier to test, reuse, and document. But something is missing. In the quest for correctness we have denied ourselves a crucial (and fun!) aspect of programming: interactivity, visualizing, debugging and just plain playing around in your environment.

UPDATE FROM DEECH: "I said in my talk at 21:32 that @pharoproject GC was simple mark-and-sweep & not great. I have been informed by the implementor that I am wrong & recent work makes latencies…
