<p>
The range expression <code>x</code> is evaluated once before beginning the loop,
with one exception: if at most one iteration variable is present and
<code>len(x)</code> is <a href="#Length_and_capacity">constant</a>,
the range expression is not evaluated.
</p>

<p>
Function calls on the left are evaluated once per iteration.
For each iteration, iteration values are produced as follows

    * --alpha-endpoint-reconciler-type=(master-count, lease, none) (default
    * "master-count"). The original reconciler is 'master-count'. The 'lease'
    * reconciler uses the storageapi and a TTL to keep alive an endpoint within the
    * `kube-apiserver-endpoint` storage namespace. The 'none' reconciler is a noop
    * reconciler that does not do anything. This is useful for self-hosted

   * The returned list should be used once and discarded. For any usages beyond that, pass the

   * ImmutableList.copyOf} and use that list instead.
