T4 models and empty column names

[ghost]

Create procedure:

create procedure x_select_implicit_column
as
begin
select 123
end
go

In this case T4 models generates wrong next output:

#region x_select_implicit_column

public partial class x_select_implicit_columnResult
{
    public int  { get; set; }
}

public static IEnumerable<x_select_implicit_columnResult> x_select_implicit_column(this DataConnection dataConnection)
{
    return dataConnection.QueryProc<x_select_implicit_columnResult>("[x_select_implicit_column]");
}

#endregion

UPD: Of course there can be many column names without names (generate new names?). It is hard to diagnose (without knowledge of procedure for which failed generation). It is just from existing production database.
