Alternative HtmlHelper Syntax

syntax.cshtml

@using (Html.BeginRouteForm(Route.Stuff, FormMethod.Get, new {@class = "myForm", data_hello = "this"}))
{
    ...
}
@using (Html.Form.Method(FormMethod.Get).Src(Route.Stuff).Class("myForm").Data_Hello("this"))
{
    
}

For a textbox, it could be:

@Html.TextBoxFor(x=>x.Name, new { type = "number", @class = "long", data_hello = "this", disabled = "disabled"})

@Html.Input(x => x.Name).Type("number").Disabled.Class("long").Data_Hello("this");

Or maybe just make the attributes using text:

@Html.Input(x => x.Name).Custom("type='number' class='long' data-hello='this'")
