Thanks for this--I mentioned finagle to jcoglan on twitter yesterday after I read his blog post, and I don't think he was aware of the similarities. I actually didn't know about fu…

Why has arithmetic become the universal example of currying and partial function application? Examples: "Currying", Section 9.3 of Programming in Scala (addition); Ruby 1.9.3 docum…

well, I hate to beat a dead horse, but here's a one-liner (ruby): (map1.keys | map2.keys).map(&:to_s).sort.join(", ").instance_eval { empty? ? " " : self }

so this is horribly non-idiomatic ruby, but it was fun p ->(*_) { _.reduce({}, :merge).tap { |_| return " " if _.empty? }.keys.uniq.map(&:to_s).sort.join(", ") }.({c:3,d:4,b:2}, {f…
