Ruby Currying

• raganwald 17y ago
  As mentioned elsewhere, is this currying? Or partial application? Currying: lambda { |x,y| x + y }.curry => lambda { |x| lambda { |y| x + y } } Partial Application lambda { |x, y| x + y }.apply(2) => lambda { |y| 2 + y } And given #curry, #apply is trivial: class Proc; def apply(param); self.curry.call(param); end end ...or at least, that's my understanding...

    i think you're right.

  After learning about these concepts in Haskell, the Ruby code seems downright ugly (I never thought I'd say that)... but still probably quite useful in some cases.
