Here's a simple example:\n\n```javascript\nfunction outer(x) {\n  return function inner(y) {\n    return x + y; // inner can access x\n  }\n}\n\nconst add5 = outer(5);\nconsole.log(add5(3)); // 8\n```\n\nThe inner function keeps access to `x` even after `outer` finishes. Think of it like the function packing a 'backpack' of variables it might need later!"

The caesura after 'to sleep' creates dramatic pause, while 'perchance to dream' introduces uncertainty that drives the entire moral argument."

Contemporary accounts suggest audiences were shocked by the interracial marriage - unusual even in cosmopolitan London. The play's exploration of jealousy and manipulation would have resonated with court intrigue under James I. Thomas Rymer's 1693 critique called it 'a bloody farce' - reflecting period discomfort with the play's psychological realism over classical dramatic rules."
