monarch_dodra: I have just given some solutions in D.learn.
So here's what I'm thinking: Let's do this, but also using each/tee/tap/consume/walk (and others?)!I think this "real world" scenario is a good bench for seeing the effects of mixing imperative-style statements into a functional-style wrapper.
As I explained in a precedent post in this thread it's hard to design something if you don't try to use it, even something simple as a each(). So I approve such exercises.
