From: Robert Griesemer Composite literals
generates a pointer to a unique variable initialized
with the literal's value.
var pointer *Point3D = &Point3D{y: 1000}+
+Note that the zero value for a slice or map +type is not the same as an initialized but empty value of the same type. +Consequently, taking the address of an empty slice or map composite literal +does not have the same effect as allocating a new slice or map value with +new. +

The length of an array literal is the length specified in the literal type. If fewer elements than the length are provided in the literal, the missing
