There is no free lunch. WASM just means another lowest common denominator abstraction for FFI. I'm also looking forward to WASM getting actually good so .NET could properly target it (because shipping WASM-compiled GC is really, really painful, it works acceptably today, but could be better). Current WasmGC spec is pretty much unusable by any language that has non-primitive GC implementation.

Just please don't run WASM on the server, we're already getting diminishing generational performance gains in hardware, no need to reduce them further.

The exports in the examples follow C ABI with respective OS/ISA-specific calling convention.
