structs

// Just a collection of fields
type Somename struct{
    a int
    b int
    c, d string
}
...
// Explicit instantiation
var s = Somename{3, 4, "c", "d"}
// Access the fields with dot notation
s.b = 10
// Access to fields via pointers is implicit
p := &s
p.c = "Pointed"
fmt.Println(s)       // {3 10 pointed d}
// Variables can be named during instantiation
// This allows for implicit defaults
t := Somename{b: 17, c:"Set"}
fmt.Println(t)       // {0 17 Set  }
