I can do:
register: result=std_out|to_json
Or some such?

Yes. That's my specific problem.
More generally, it raises the question: how can I operate on the results of
an action (in code I write in playbooks and tasks vs modules)? The scope of
what's possible isn't clear to me from the docs. Can I say, filter a list
of results (e.g. from ec2_describe) and store the results in another list
with an named value?
I'm somewhat open to it, but also think that because it's possible to do

Doesn't this only assign a fact to the target host?
In many cases, that's not the desired behavior. Suppose I want to collect a
list of RDS instances ids by tag and perform simple operations on them over
and over?
Being able to:
- add variables
- trigger conditions
- filter output, join lists... etc...
would be tremendously useful. I guess something like:
- hosts: localhost
- name: Describe instances
hosts: localhost
gather_facts: false # Prevents immediately logging in to hosts
tasks:
- command: aws ec2 describe-instances
after: >
some python code to filter the results
some python code to register 5 groups
some python code to register 2 variables (register)
isn't possible?
This is just an example, I'm already using ec2.py for much of this. But
more fined-grained controlled is required (such as having tasks
conditionally execute or wait on ec2_instance states which may change in
response to prior tasks).
