Context

• node version: 8.5.0
• joi version: 11.0.3
• environment (node, browser): node and browser
• used with (hapi, standalone, ...): as custom koa middleware or standalone
• any other relevant information:

What are you trying to achieve or the steps to reproduce ?

Simply importing any of joi types produces an error. It started happening with v11. this seems to be undefined.

import { string, number, any, object } from 'joi'

If I import Joi from 'joi' instead, everything works again.

Which result you had ?

...\node_modules\joi\lib\index.js:28
    if (this._defaults) {
            ^

TypeError: Cannot read property '_defaults' of undefined
    at internals.applyDefaults (...\node_modules\joi\lib\index.js:28:13)
    at root.object (...\node_modules\joi\lib\index.js:102:48)

What did you expect ?

Expected import to work as previous version.
