Here's the new test:
- set_fact:
mongodb_candidate_master: "{{mongodb_replica_set_hosts[0]}}"
run_once: true
- name: var groups.mongod_rs_member[0]
debug: var=groups.mongod_rs_member[0]
run_once: true
- shell: echo "HELLO groups.mongod_rs_member +++++++++++++++++"
delegate_to: "{{groups.mongod_rs_member[0]}}"
run_once: true
- name: var mongodb_candidate_master
debug: var=mongodb_candidate_master
run_once: true
- shell: echo "HELLO mongodb_candidate_master +++++++++++++++++"
delegate_to: "{{mongodb_candidate_master}}"
run_once: true
- name: var mongodb_replica_set_hosts[0]
debug: var=mongodb_replica_set_hosts[0]
run_once: true
- name: msg mongodb_replica_set_hosts[0]
debug: msg="{{mongodb_replica_set_hosts[0]}}"
run_once: true
- debug: msg="{{mongodb_replica_set_hosts[0]}}"
run_once: true
- shell: echo "HELLO mongodb_replica_set_hosts +++++++++++++++++"
delegate_to: "{{mongodb_replica_set_hosts[0]}}"
run_once: true
And the output:

FATAL: all hosts have already failed -- aborting

render the value as '{' just like the delegate_to.
