Preventing recursion is in this case the much bigger use than speed. I don't think, that there is a big speed difference, but there are many cases where recursion could happen (think about a = b; b = a). csfdd}|S)Ncsr |j}nr|dj}n|jj}z |}WntyNi|<}Yn0||t|f}||vrr||Stur||<|g|Ri|}|||<|SdS)Nr) memoize_cacheinference_stateKeyError frozensetitems _NO_DEFAULT)objargskwargscachememokeyrv)defaultfunctioninference_state_is_first_argsecond_arg_is_inference_stateP/var/www/html/django/DPS/env/lib/python3.9/site-packages/jedi/inference/cache.pywrappers"   z/_memoize_default..func..wrapperrrrrrrrrfuncsz_memoize_default..funcr)rrrrrrr_memoize_defaults rcsfdd}|S)Ncstdd|S)NT)rrrrrrr decorator5sz1inference_state_function_cache..decoratorrrr!rr rinference_state_function_cache4s r#csfdd}|S)Ncstd|S)Nr rrr rrr!<sz/inference_state_method_cache..decoratorrr"rr rinference_state_method_cache;s r$cCs dd}|S)NcSstdd|S)NT)rr)callrrrr!Csz8inference_state_as_method_param_cache..decoratorr)r!rrr%inference_state_as_method_param_cacheBsr&cs&eZdZdZefddZZS)CachedMetaClassz This is basically almost the same than the decorator above, it just caches class initializations.
