cannot return non-expression? Cannot return a type/struct?

golangsux.go

package models

// note we get a compilation error, shown below

import (
	nearby "huru/models/nearby"
	person "huru/models/person"
	share "huru/models/share"
)

func getModels() struct{} {
	return struct {
		Near  nearby.Map
		Pers  person.Map
		Shar share.Map
	}
}

// compilation error: 
// type struct { Near nearby.Map; Pers person.Map; Shar share.Map } is not an expression
