(Not at all urgent, just filing for future ideas. Please put in backlog.)

Currently, the atomic operation API allows only one atomic action at a time:

person = Person.all.first

# the following lines perform 3 database actions
person.set(name: "Bob")
person.unset(:first_name)
person.inc(likes: 1)

It would be nice if we had a way to lazy evaluate the actions so the run as one command: 

person = Person.all.first

person.atomic.set(name: "Bob").unset(:first_name).inc(likes: 1).perform

In the above #atomic is analogous to Enumerable.lazy method.

(Often I find that I do pull and push, set and unset, etc. together in the same places in my code, so this could have some performance advantage.)
