// In Wasmtime versions prior to 14, options passed after the module name
// could be interpreted by Wasmtime if it recognized them. As with many CLI
// tools, the `--` token is used to stop that behavior and indicate that the
// remaining arguments are for the WASM program being executed. Historically,
// we passed `--` after the module name here.
//
// After version 14, the `--` can no longer be passed after the module name,
// but is also not necessary as Wasmtime will no longer try to interpret
// options after the module name. So, we could just simply omit `--` for
// newer Wasmtime versions. But to maintain compatibility for older versions
// that still try to interpret options after the module name, we have moved
// the `--` before the module name. This appears to work for both old and
// new Wasmtime versions.
