Run a WebAssembly Module

Sum function in a WebAssembly text format module:

const string wat_sum_module =
  "(module\n" ~
  "  (type $sum_t (func (param i32 i32) (result i32)))\n" ~
  "  (func $sum_f (type $sum_t) (param $x i32) (param $y i32) (result i32)\n" ~
  "    local.get $x\n" ~
  "    local.get $y\n" ~
  "    i32.add)\n" ~
  "  (export \"sum\" (func $sum_f)))";

auto engine = new Engine();
auto store = new Store(engine);
auto module_ = Module.from(store, wat_sum_module);
auto instance = new Instance(store, module_);
auto sumFunc = Function.from(instance.exports[0]);

assert(engine.valid && store.valid && module_.valid && instance.valid && sumFunc.valid, "Could not instantiate module!");

Value[] results;
assert(sumFunc.call([new Value(3), new Value(4)], results), "Error calling the `sum` function!");
assert(results.length == 1 && results[0].value.of.i32 == 7);
