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

I am trying to use the ObjectSchema.describe function in the way that the typings suggest I could.

The object returned by ObjectSchema.describe does not match it's corresponding type definition:

import joi from 'joi'; // 17.6.0
const myObj = joi.object({foo: joi.string().description('bar')});
myObj.describe();

What was the result you got?

{ type: 'object', keys: { foo: { type: 'string', flags: [Object] } } }

What result did you expect?

An object without the keys property, matching the Description type here.
