英文:
Why does GoDoc not show interface variables?
问题
考虑以下代码片段：
package example
type Foo interface {
}
var Alpha = "alpha"
var Beta string = "beta"
var Gamma Foo = "gamma"
无论是godoc(-http=:6060)还是go doc，都完全忽略了Gamma，而Alpha和Beta当然会在输出中显示。这种行为似乎可以在任何声明为接口类型的导出变量中复现。
为什么会这样呢？
英文:
Considering the following snippet:
package example
type Foo interface {
}
var Alpha = "alpha"
var Beta string = "beta"
var Gamma Foo = "gamma"
Both godoc (-http=:6060) and go doc ignore Gamma entirely, whilst Alpha and Beta are - of course - shown in the output. This behavior seems to be reproducible with any exported variable that is declared to be an interface type.
Why?

在我的系统上没有确认。我可以看到所有内容，包括Gamma。
变量Gamma在类型Foo定义之后。
但是在我的系统上安装了一个golang的开发版本：
go version devel +1140207a3395 Wed Nov 20 13:47:37 2013 -0800 linux/amd64
英文:
Unconfirmed at my system. I see all, including Gamma.
Var Gamma is placed after type Foo definition.
But at my system a devel version of golang is installed:
go version devel +1140207a3395 Wed Nov 20 13:47:37 2013 -0800 linux/amd64
