Hello  
My real desire is to limit the number of hosts for a playbook.  
Since --limit does not support that (AFAIK), I’m using A[0-x] for this, but here is the thing:  
My playbook limit the hosts to A:&B  
I would like to do something like : --limt “(A:&B)[0-x]”, in the CLI, limiting the number of host in the intersection of A and B.  
A[0-x]:&B, A:&B[0-x] or even A[0-x]:&B[0-x] does not provide this.

Any advice?
