Closed Unassigned: fail to compile by specifying the @model [1706]

fail to compile if you specify a Tuple of four or more arguments to @model

OK
```
@model Dictionary<int, Tuple<int, int, int>>
```

NG
```
@model Dictionary<int, Tuple<int, int, int, int>>
```

If you look at the output of the Razor compiler, specify the type argument is broken
```
public class _Page_Views_Home_Index_cshtml : System.Web.Mvc.WebViewPage<Dictionary<int {
```
Comments: This is a known issue, and the alternative is to specify a strong type.
