CLN: no need to call _wrap_results in nanvar
this is likley true for only float returning methods, e.g. sem, kurt, skew as well (though i don't think its actually a big deal if you leave this here). > this is likley true for only float returning methods, e.g. sem, kurt, skew as well (though i don't think its actually a big deal if you leave this here).

_wrap_results is only relevant for td64/dt64, so my plan is to combine it with _mask_datetimelike_result (will end up being a decorator).  You're right that its harmless here. Closing in favor of #37723
