List input should accept any type

[Lutymane]

Hi, I tried to make a list input with function values and it failed with Error: No matching controller for 'op'.

Current workaround is setting initial value to 0 (but basically any number or string), as the type is checked only upon creation and it just works perfectly afterwards.

So the issue is there seem to be no reason to limit lists to only numbers and strings and do any type checking.

Min repro:

const sum = (a, b) => (a + b);
const sub = (a, b) => (a - b);

let params = {
    op: sum,
};
const pane = new Pane();
pane.addInput(params, "op", {
  label: "operation",
  options: {
    sum,
    sub,
  }
});

But if it's function, it could not be serialized right?
It will cause headache to serialize that... I think it's better to do it with enum, and select the appropriate function from it.

Technically, function can be serialized by storing the code as string Function.toString() and then parsed back with eval.

But I don't think the functions should be serialized at all and just be skipped like in JSON
