let foo = trick(require('foo'));
var foo = require?.('foo');
const foo = require?.('foo');
let foo = require?.('foo');
let foo = trick(require?.('foo'));
let foo = trick?.(require('foo'));
const foo = require('./foo.json') as Foo;
const foo: Foo = require('./foo.json').default;

// const foo = <Foo>require('./foo.json');

// const configValidator = new Validator(require('./a.json'));
// configValidator.addSchema(require('./a.json'));
