// function declarations currently call [[Set]] instead of [[DefineOwnProperty]]
// in VM contexts, which violates the ECMA-262 specification:
// https://tc39.es/ecma262/#sec-createglobalfunctionbinding

const ctx = vm.createContext();

});

vm.runInContext('function x() {}', ctx);
assert.strictEqual(typeof ctx.x, 'function');
