I was hoping to write a utility that adds some properties to a function, similar to how hoox adds a hook property. This utility is used in the context of secret-stack, so the function is eventually wrapped using hoox which doesn't currently preserve these properties. Proposed here is a backwards-compatible change to preserve the original function's own properties. Here's a little example to illustrate:

  var add = function (a, b) {
    return a + b
  };

  add.operation = 'addition'

  var h = Hoox(add)

  t.equal(h.operation, 'addition')
