memoize(func)

Signature: memoize(func: Callable[..., Any]) -> Callable[..., Any]

A simple memoization decorator that caches results by arguments. Uses a tuple of args and a frozenset of kwargs items as the cache key.

Example

@memoize
function fib(n) returns int {
    return n if n < 2 else fib(n-1) + fib(n-2);
}
