剃刀模板委托，内部如何工作？

Question

I'm reading this excellent article regarding razor template delegate. http://www.prideparrot.com/blog/archive/2012/9/simplifying_html_generation_using_razor_templates

While I understand how it's used, as in

Func<dynamic, HelperResult> variable = @<var>@item.ProductName</var>

My question is, how exactly razor engine translated " @<var>@item.ProductName</var> " into a delegate in the background? As in

Func<dynamic, HelperResult> variable = delegate(dynamic x)
{
   (what goes on in here?)
}

is @item a reserved keyword that razor parses out? Can it be used in any other convention? say @column or @row or any other ways?

Thanks a lot. Like I said, i'm more interested in how razor view engine translated the template statements into actual code in the background.

[Edit]. Thanks to Brad for pointing out Andrew's article. so above statement " @<var>@item</var> " will translate into

Func<dynamic, HelperResult> variable = delegate(dynamic item)
{
     return new Microsoft.WebPages.Helpers.HelperResult(__writer => {
     @__writer.Write(" ");
     @__writer.Write("<var>");
     @__writer.Write(item.ProductName);     <--- what's happening here?
     @__writer.Write("</var>");
}

So I see razor automatically parses out @<var> and </var> into separate strings and such, my question in regards to "item.ProductName" is..suppose "item" is a "Proudct" type, then is the following what razor is trying to do?

First, razor parses "@item.ProductName" separated by comma ".", get "item" and "ProductName".

Then because of the "dynamic" parameter, in the background, .NET will attempt to find the value of the property "ProductName" of the item "Product"?

Thanks

Never mind. I don't know why i didn't make the connection.

I asked another question in regards to DynamicObject DynamicObject? How does the following code work? and @Alxandr explained this regarding "dynamic". So essentially, it becomes

dynamic item = new Product(...);
String ProductName = item.ProductName;

So in essence, "dynamic" parameter in the background use CSharpGetMemberBinder and through reflection, figure out the "ProductName" of the object "Product".

razor template has a pretty brilliant design
