How can write-only properties be created?

[mojca]

I see class_::def_property() and class_::def_property_readonly() to create read-write and read-only properties, but I miss something for write-only properties. Is this something that would first have to be implemented inside pybind11?

Of course I can always leave a setter method and call object.set_something(value), but it would be nice in a way to have complete support for properties.
