[julia-users] Re: Equivalent of c++ functor objects, std::bind, and lambdas

[Noah Brenowitz]

function make_counter(x)
  return (delta) -> begin
    x[1] += delta
    x
  end
end

x = [0]

c0 = make_counter(x)
c1 = make_counter(x)


c0(1) # [1]
c1(1) # [2]
c0(1) # [3]
c1(1) # [4]


That seems to be the case with scalars, but not with a vector (or other 
objects I assume). See the above code
