Cannot use fields of anonymous field in struct literal

[gopherbot]

by kirklin.mcdonald:

The following code gives the following error:

$ cat test.go
package test

type A struct {
    X int;
}

type B struct {
    A;
    Y int;
}

var b = B{X: 20, Y: 12}
$ 6g -o test.6 test.go
test.go:12: b.X undefined (type B has no field X)

Given that X is a valid field of B, I would expect this to be a valid 
struct literal.

Additional information:
$ echo $GOARCH $GOOS
amd64 linux
$ hg log -l1

Comment 1:

Struct literal syntax does not dig into embedded fields: the keys are field names, not 
selectors.  Instead, you can give a literal for the entire embedded structure:
var b = B{A:A{X:20}, Y:12}
This should probably be pointed out explicitly in
http://golang.org/doc/go_spec.html#Composite_literals

Labels changed: added language-change.

Owner changed to g...@golang.org.
