// once will only execute the given callable if the given key didn't exist yet
$expensiveFunction = function() {
   return rand();
});
blink()->once('random', $expensiveFunction); // returns random number
blink()->once('random', $expensiveFunction); // returns the same number

blink()->has('key'); // Returns true
blink()->has('prefix*'); // Returns true if the blink contains a key that starts with 'prefix'

// Specify a default value for when the specified key does not exist
blink()->get('non existing key', 'default') // Returns 'default'

blink()->put('anotherKey', 'anotherValue');

// Put multiple items in one go
blink()->put(['ringo' => 'drums', 'paul' => 'bass']);

blink()->all(); // Returns an array with all items

blink()->forget('key'); // Removes the item
blink()->forget('prefix*'); // Forget all items of which the key starts with 'prefix'

blink()->flush(); // Empty the entire blink

blink()->flushStartingWith('somekey'); // Remove all items whose keys start with "somekey"

blink()->increment('number'); // blink()->get('number') will return 1 
blink()->increment('number'); // blink()->get('number') will return 2
blink()->increment('number', 3); // blink()->get('number') will return 5

// Blink implements ArrayAccess
blink()['key'] = 'value';
blink()['key']; // Returns 'value'
isset(blink()['key']); // Returns true
unset(blink()['key']); // Equivalent to removing the value

// Blink implements Countable
