Edges of Python Three Radical Python Hacks for Fun and Profit
summary
Three concrete hacks: a tiny sync shim that starts coroutines with coro.send(None) and replaces async streams with blocking sockets to reuse one async codebase as a synchronous client (works for simple network stacks but loses create_task/timeouts and adds marginal call overhead); using an immutables persistent map (HAMT) to get structural sharing instead of expensive full dict copies (copies become noticeable around ~10k entries, ~1 ms); and a value-dispatch pattern (dispatch on values not just types) with a reference implementation in the EdgeDB repo.
