# Below is a huge hack for dynamically building a list of workers and finally assigning it to `matrix_synapse_workers_enabled_list`.
#
# set_fact within a loop does not work reliably in Ansible (it only executes on the first iteration for some reason),
# so we're forced to do something much uglier.
