Context

• node version: v9.6.0
• joi version: 13.4.0
• environment (node, browser): node
• used with (hapi, standalone, ...): hapi
• any other relevant information:

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

const some_common_schema = Joi.number()
  .integer()
  .positive()
  .example(15);
const other_schema = some_common_schema.required().example(200);

Which result you had ?

other_schema did have example value of 15. Console logging the other_schema shows that the id 200
is pushed to array _examples: [ 15, 200 ],

What did you expect ?

I expected it to replace the old example value with the new one.
