codeclimate/codeclimate-rubocop

This cop checks for uses of `and` and `or`, and suggests using `&&` and
`|| instead`. It can be configured to check only in conditions, or in
all contexts.

### Example: EnforcedStyle: always (default)
    # bad
    foo.save and return

    # bad
    if foo and bar
    end

    # good
    foo.save && return

    # good
    if foo && bar
    end

### Example: EnforcedStyle: conditionals
    # bad
    if foo and bar
    end

    # good
    foo.save && return

    # good
    foo.save and return

    # good
    if foo && bar
    end
