Going through the process of the example for my message just now made me
think more about this function. Suppose it:

1. Accepted an array of substitutions rather than a rest parameter, and

2. Accepted an optional mapping function

Then, what I wrote on my last message as:

```js
const escape = (strings, ...subs) => {
    return String.cook(strings, ...subs.map(escapeHTML));
};
```

would be

```js
const escape = (strings, ...subs) => *String.cook(strings, subs,
escapeHTML)*;
```
(http://jsfiddle.net/n6p7xcvm/1/)

...while still supporting the earlier usage (just without spread) if
desired.
