WASM in your wheel?
summary
Uses WebAssembly to avoid building many platform wheels by shipping a .wasm alongside Python code: mpy-cross compiled to .wasm and loaded with runtimes wasm3/wasmtime/pyodide. Claims: near-native performance with wasmtime/wazmer, single-source build change (swap compiler, add emscripten flags) — one-line change to Makefile — and three interchangeable backends implemented. Works for the MicroPython cross-compiler, but reduces explicit target set (≈7 vs 24), needs the .wasm in the wheel, and debugging and runtime selection remain awkward.
