How to use the @glimmer/opcode-compiler.Macros function in @glimmer/opcode-compiler

constructor(resolver: RuntimeResolver) {
    const program = new Program(new LazyConstants(resolver));
    const macros = new Macros();
    populateMacros(macros);
    this.program = program;
    this.macros = macros;
    this.resolver = new CompileTimeLookup(resolver);
    this.Builder = LazyOpcodeBuilder as OpcodeBuilderConstructor;
  }

constructor(isInteractive: boolean) {
    let macros = new Macros();
    populateMacros(macros);
    this.compiler = new LazyCompiler(new CompileTimeLookup(this), this, macros);
    this.isInteractive = isInteractive;

    this.builtInModifiers = {
      action: { manager: new ActionModifierManager(), state: null },
      on: { manager: new OnModifierManager(isInteractive), state: null },
    };
  }
