In general, identifiers cannot be accurately resolved without type information.
      Consider, for example, the identifier <code>K</code>
      in <code>T{K: ""}</code>: it could be the name of a local variable
      if T is a map type, or the name of a field if T is a struct type.

      New programs should use the <a href='/pkg/go/types'>go/types</a>
      package to resolve identifiers; see

struct {
	T1        // field name is T1
	*T2       // field name is T2
	P.T3      // field name is T3
	*P.T4     // field name is T4
	x, y int  // field names are x and y
}
</pre>

<p>
The following declaration is illegal because field names must be unique
in a struct type:
</p>

<pre>
struct {
	T     // conflicts with embedded field *T and *P.T

struct {
	T1        // field name is T1
	*T2       // field name is T2
	P.T3      // field name is T3
	*P.T4     // field name is T4
	x, y int  // field names are x and y
}
</pre>
