to this effect, essentially)

If LiteralType is a TypeName, the denoted type must be an array, map, or
structure. The types of the expressions must match the respective key, element,
and field types of the literal type; there is no automatic type conversion.

Composite literals are values of the type specified by LiteralType; that is
a new value is created every time the literal is evaluated. To get
a pointer to the literal, the address operator "&" must be used.
Implementation restriction: Currently, map literals are pointers to maps.
