-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
+names as the fields.
