Internally node shouldn't rely on user provided functions/objects having 'normal' values.

e.g.

a = function() { console.log(1,2,3)}; a.call = "some value" setTimeout(a, 100); true

Output:

TypeError: callback.call is not a function at ontimeout (timers.js:386:14) at tryOnTimeout (timers.js:250:5) at Timer.listOnTimeout (timers.js:214:5) 

For this example, node's timers.js should be using Function.prototype.call or Reflect.apply
