[kthjm]

fixes #3

I like _owner, does it pass all your testing?

[kthjm]

test is passed. should i update test.js too ?

in my local:

t.test('should support `React.createElement` in dev', function (st) {
    process.env.NODE_ENV = "development";
    /* test */
    process.env.NODE_ENV = undefined;
    st.end();
});

t.test('should support `React.createElement` in prod', function (st) {
    process.env.NODE_ENV = "production";
    /* test */
    process.env.NODE_ENV = undefined;
    st.end();
});

[wooorm]

Would the tests actually run the React code differently? Or does React do funky stuff with building?

If so, yes please!

P.S. Cleaner: currentEnv = process.env.NODE_ENV; /*...*/; process.env.NODE_ENV = currentEnv;.
