embedded struct fields are not populated

[BrianHicks]

Unmarshalling embedded struct fields works in encoding/json but not HCL (as of 5b7dbf7). Here's the code using encoding/json: https://play.golang.org/p/rrXXw7j8VM. The equivalent in HCL follows:

package main

import (
    "fmt"

    "github.com/hashicorp/hcl"
)

type Inner struct {
    Dependencies []string `hcl:"dependencies"`
}

type Outer struct {
    Inner

    Name string `hcl:"name"`
}

func main() {
    x := new(Outer)

    err := hcl.Unmarshal(
        []byte(`
name = "test"
dependencies = ["a", "b", "c"]
`),
        x,
    )

    fmt.Printf("%+v %v\n", x, err)
}

Would this be a contribution y'all are interested in? If you are and you could point me toward a good place to get started, I'd appreciate it :)

Update: looks like this is possible, but I had to dig through the code:

type Outer struct {
    Inner `hcl:",squash"`
}

I couldn't find any documentation for this, and as above encoding/json does it by default. Was there a rationale for the difference? Either way, happy to contribute documentation. Easier than a code fix. ;)

Was this broken? doesn't seem to work in v2
There is a huge problem with documentation for HCL

panic: invalid hcl field tag kind "squash" on ...

faced the same issue with v2

type Outer struct {
    Inner `hcl:",remain"`
}

works for me 😉
