Three previous attempts at forcing -std=c++20 (global, flags-D, env CXXFLAGS) all failed identically with src/ir/effects.h:572: error: no member named 'contains' in 'std::set' which on its face looks like a -std= issue. Checking how nixpkgs handles binaryen (per the updated org memory quirks: ALWAYS look at upstream packagers FIRST): they ship empty cmakeFlags. Their stdenv's cc-wrapper guarantees clang picks up the SAME gcc derivation's libstdc++ headers. That's what's actually missing here — pkgx clang on Linux falls back to the host /usr/include/c++/12/ (Ubuntu 22.04 ships GCC 12 whose libstdc++ predates the back-port of `contains` to C++17/feature-test gates). Fix: add gnu.org/gcc as a Linux build dep and -isystem its libstdc++ include dir explicitly. clang then sees the modern / headers, std::set::contains resolves, build completes. Darwin keeps the simple cmake invocation: libc++ from llvm.org is already wired through pkgx's clang properly there.
