We can initializing a data structure (struct, enum, union) with named fields,
by writing `fieldname` as a shorthand for `fieldname: fieldname`. This allows a
compact syntax for initialization, with less duplication:
Initialization of a data structure (struct, enum, union) can be simplified if
fields of the data structure are initialized with variables which has same
