I still believe that imperative is the best paradigm to start programming. I.e. once you understand all the subtleties of for/while and branching, you can undertand a list comprehension as an abstraction on top of that, applicable for certain situations. In that light I think OP's tool is exactly what one needs to get going. A similar approach for those mounting towards FP would be certainly nice though, but it would have a completely different target demographic. Also it seems to me that languages like Haskell and F# are better for just learning FP.
