Maybe-type
Fixtype of optional Syntheto types.
This is an option type introduced by fty::defoption.
Note that defoption is just a wrapper for fty::defflexsum, so there are :none and :some member
types, a case macro, and so forth.

- :some → maybe-type-some
- An available maybe-type, i.e., Just val or Some val.
