How to use the @glimmer/program.patchStdlibs function in @glimmer/program

concatStatements(context, actions);

    let handle = context.encoder.commit(context.syntax.program.heap, m.size);

    if (typeof handle !== 'number') {
      return handle;
    }

    this.compiled = handle;

    if (DEBUG) {
      debugCompiler(context, handle);
    }

    patchStdlibs(context.syntax.program);
    return handle;
  }
}

function maybeCompile(
  compilable: CompilableTemplateImpl,
  context: SyntaxCompilationContext
): HandleResult {
  if (compilable.compiled !== null) return compilable.compiled!;

  compilable.compiled = PLACEHOLDER_HANDLE;

  let { statements, meta } = compilable;

  let result = compileStatements(statements, meta, context);
  patchStdlibs(context.program);
  compilable.compiled = result;

  return result;
}
