This provides a more concise syntax for ensuring a function is called only once. After extending the prototype, you can call `.once()` on any function to get a version that executes only on its first invocation.

```javascript
// only has to be done once
require('once').proto()

function load (file, cb) {

cache.set("key", "value")
cache.get("key") // "value"

// non-string keys ARE fully supported
// but note that it must be THE SAME object, not
// just a JSON-equivalent object.
var someObject = { a: 1 }
cache.set(someObject, 'a value')
// Object keys are not toString()-ed
cache.set('[object Object]', 'a different value')
assert.equal(cache.get(someObject), 'a value')
