go 1.10 encoding/json Decoder.DisallowUnknownFields

Go 1.10 was released today and an addition to the core library encoding/json package caught my eye

func (dec *Decoder) DisallowUnknownFields()

DisallowUnknownFields causes the Decoder to return an error when the destination is a struct and the input contains object keys which do not match any non-ignored, exported fields in the destination.
