Tip Apex: Select * from X on apex (SOQL)

I’ve faced many times two problems on SOQL queries:

1. They have not * (star) operator and hence it is really tough to list all fields on large objects.
2. If you try to modify a field name or delete or update the type, salesforce won’t allow you if it is referenced on the code. It is really painful on deploys.

As a best practices when I have to retrieve all fields I use this simple function.
