JS Pop Quiz: How well do you know your functions?

Given an Array of Functions fns, what argument(s) can you pass to fns.forEach such that each function in fns will execute, in order, without creating any anonymous (or named) functions or invoking the Function constructor?

Conditions

Do not use the function keyword, or arrow functions () => .
Do not invoke the Function constructor.
Do not use method definitions.
Function#bind & friends on the Function.prototype are ok.

	// take SVG commands and draw this path to HTML5 canvas

	// commandList should look like that: [ { marker: "M", values: [ 10, 10 ] },
	// { marker: "l", values: [ 5, 7 ] },
	// { marker: "C", values: [ -5, 7.2, .3, -16, 24, 10 ] },
	// . . .
	// { marker: "z", values: [ ] } ]

	// there's another gist which has the code to parse SVG paths:
