Setting: default

default [PACKAGE:]METHOD can be defined as method comment.

By default the target object is initialized with zero values | Go docs. With default you can instruct Goverter to use METHOD as default target value or constructor for the target value.

The METHOD may be everything supported in extend Signatures with the addition that the source parameter is optional.
