Not related to with_entries, but I didn't see anywhere else in this thread that mentioned dealing with awscli output

from_entries handles nicely the Tags in a lot of awscli output, you can do things like

    aws ec2 describe-instances | \
        jq '.Reservations[].Instances[] | 
            {Role: .Tags | from_entries | .role,
             Name: .Tags | from_entries | .name,
             Id: .InstanceId}' \
        -C -c | sort | less -R

to get a summary of all your instances sorted by role.

thanks for the suggestion, i will add another example like this.
