All about decorators
summary
Shows exactly what gets built and what works: writes a bunch of decorators that wrap functions, uses splat args and double-splat kwargs so wrappers accept any signature, demonstrates functools.wraps to preserve names, uses nonlocal counter storage for per-decorator state, implements memoize and a timing logger that appends to timing.txt, a once-per-minute gate that raises an error when called too soon, and class decoration that stamps instances with creation time — all examples run live and produce the promised files and outputs.
