* its members. This requires sol-flow/wallclock.h to be
* avaiable, but is more efficient since goes straight to the
* point, no parsing or memory allocations. It would look
* like:
*
* #include <sol-flow/wallclock.h>
*
* struct sol_flow_node_type_wallclock_minute_options opts =
* SOL_FLOW_NODE_TYPE_WALLCLOCK_MINUTE_OPTIONS_DEFAULTS(
* .send_initial_packet = true);

* type->default_options and
* type->description->options and manually
* create the structure in runtime. This demands
* SOL_FLOW_NODE_TYPE_DESCRIPTION_ENABLED, but may be useful
* when converting from a different representation, like a
* language binding such as JavaScript or Python where one can
* get an object, hashmap or dictionary and convert straight
* to the C structure needed by the flow node type.
*
* 3 - use helper sol_flow_node_named_options_init_from_strv() and
* sol_flow_node_options_new(), giving it an array of
* "key=value" strings. It will do the work described in #2
* for us, thus also depends on
* SOL_FLOW_NODE_TYPE_DESCRIPTION_ENABLED.
*
* We'll use approach #3 since it is simpler. Language bindings
* should go with option #2 and those that want to squeeze the
* size and get performance should consider #1.
