Summary
functools.partial and functools.lru_cache were deferred from stdlib Phase 2 because they require features not yet available in Sharpy:
partial(func, *args): Needs a runtime callable wrapper that captures partial arguments. Challenging with Sharpy's static type system — requires creating a generic wrapper or using Func<> delegation.lru_cache(maxsize=128): Needs decorator argument support in the compiler. Currently decorators are recognized but decorator arguments are not fully supported.cache: Alias for lru_cache(maxsize=None), blocked by same issue.
Current State
functools.reduce() and functools.cmp_to_key() are implemented and workingpartial, lru_cache, cache are not implemented
Possible Approaches
partial: Could use object[] captured args with runtime dispatch, or generate specialized Func<> wrapperslru_cache: Requires compiler support for @decorator(args) syntax generating wrapper code
Context
Deferred from stdlib Phase 2 plan.
