From c8d087ab16dae176e2311c6bf77ec339a09071ab Mon Sep 17 00:00:00 2001 From: madhusudanpatnaik Date: Tue, 20 Oct 2026 07:43:25 +0000 Subject: [PATCH] perf(python): look exact names up in an index in the module-call arm Filtering the children that share a folded key on every call made N calls to N same-key names O(N^2) (2,000 case-variant calls: 1.7 s vs 0.8 s on v8). The exact-name index is built with the folded one, so the lookup is O(1); pydantic's graph is identical to the scanning version.
