Gin: Binding array of objects from post form

[Ragnar-BY]

Description

Are there a possibility to bind post form values from array of objects using gin?

How to reproduce

I have post form like

<input type="text" name="class">
<!-- first student -->
<input type="text" name="students[][first]">
<input type="text" name="students[][last]">
<input type="text" name="students[][age]">

<!-- second student -->
<input type="text" name="students[][first]">
<input type="text" name="students[][last]">
<input type="text" name="students[][age]">

And go code

type Student struct {
    First string `form:"first"`
    Last  string `form:"last"`
    Age   int    `form:"age"`
}
type Class struct {
    Class    string    `form:"class"`
    Students []Student `form:"students[]"`
}
func Handle(c *gin.Context) {
    err := c.Request.ParseForm()
    if err != nil {
        log.Fatal(err)
    }
    class:= new(Class)

    err = c.Bind(class)
    if err != nil {
        log.Fatal(err)
    }
    log.Println(c.Request.PostForm)
    log.Println(class)
}

I receive next output

map[students[][first]:[John Jack] students[][last]:[Johny Jacky] students[][age]:[20 30] class:[myclass]]
&{myclass []}

But I expect to receive array of structs Student and get output like

&{myclass [{John Johny 20} {Jack Jacky 30}]} 

How is it possible to do it?

Can't wait to see this supported! Coming from PHP, things like this were very common.
