I realized that the logic of setting local.__this__ works better than I thought it did: it's set in Identifier, so there's no need to have _resolve and _yield methods of Entity and Attribute set it again. I did some testing and the results are very promising because not calling any additional methods makes getting entities faster.

Holy electrons, getting just got 4 times faster! Mean times for settings.lol (via make perf), n = 50 (500x) master patch diff % diff ------------------------------------------ get 127 32 -95 -75%
