Stacked decorators and __name__ without wraps

Question

Accepted Answer

Without `@wraps`, each decorator's inner `wrapper` overwrites the function's `__name__`. After `@italic` wraps `title`, `__name__` is `'wrapper'`. After `@bold` wraps that, `__name__` is still `'wrapper'` (bold's wrapper). For the output, decorators apply bottom-up: `italic` wraps first producing `hello`, then `bold` wraps that producing `hello`.
