spec: direct reference to embedded fields in struct literals #9859

(Status: referred from LanguageChange to Proposal. --adonovan)

Consider

type E struct {
    A int
}

type T struct {
    E
}

This works:

T{E: E{A: 1}}

This does not:

T{A: 1}

Makes some struct literals more verbose than they need be, and makes them asymmetrical to their usage (where you can access the embedded struct's fields directly).

Can we allow it?
