C's union types are represented as a Go byte array with the same length.

Go structs cannot embed fields with C types.

Go code cannot refer to zero-sized fields that occur at the end of
non-empty C structs. To get the address of such a field (which is the
only operation you can do with a zero-sized field) you must take the
address of the struct and add the size of the struct.

Cgo translates C types into equivalent unexported Go types.

            this.seq = 0; // zero for seq means that this token is the original of synonyms
