使用基本模板将字符串解组到地图结构（模板解析的反向过程）

I'm curious to see if there is a way to marshal a map or struct from a string and a Go Template (the reverse of template.Execute)

For example, let's say we have the following template for a filename pattern

const NameTemplate = `{{ .Os.Type }}/{{ .Os.Variant }}!{{ .Os.Version }}!{{ .Name }}!{{ .Version }}`

And let's say we have the following map (using a structure in my solution, but I'll use a map here for simplicity)

data := map[string]interface{}{
    "Name": "some-name",
    "Version": "1.0",
    "Os": map[string]interface{}{
        "Type": "linux",
        "Variant": "debian",
        "Version": "9.0",
    },
}

Doing a tmpl.Execute(NameTemplate, data) will result in linux/debian!9.0!some-name!1.0

Now what if we had that string linux/debian!9.0!some-name!1.0 and the template defined above NameTemplate. Is there a simple way to do obtain a map (or struct) like the one defined in data?
