For type switches where the targets are interface types, call into the runtime once instead of doing a sequence of assert* calls. name old time/op new time/op delta SwitchInterfaceTypePredictable-24 26.6ns ± 1% 25.8ns ± 2% -2.86% (p=0.000 n=10+10) SwitchInterfaceTypeUnpredictable-24 39.3ns ± 1% 37.5ns ± 2% -4.57% (p=0.000 n=10+10) Not super helpful by itself, but this code organization allows followon CLs that add caching to the lookups.
