And now if you call Example("Hello", "world"), does the first "Hello" belongs to value or to otherValues?
You could argue that the types in your examples are different, but the rules become too complicated to follow. For example repeated parameters often used with Any type. This example case class Example(value: Option[String] = None, otherValues: Any*) has different types, but still struggles with the same problem

 Q:

Check if dataGridView is empty

I am in need of a simple way for checking if my datagridview is/isn't empty.
The Rows.Count does not satisfy me, because my program starts with 2 empty rows,
 and in the future the datagridview could be populated and then the count
 does not affect anything
(If the users deletes a section but there are more than 2 rows present).
Is there anyway of checking this?

A:

well these are the checking options for whether  datagrid view  is empty or not......
if(DataGridView1.Rows.Count == 0)
{
    MessageBox.Show("DataGridView is empty");
}

2). You can check the DataTable or DataSet which binds to 
DataGridView:
if(dt == null)
{
   MessageBox.Show("DataGridView is empty");
}

if(ds == null)
{
   MessageBox.Show("DataGridView is empty");
}

you can check with datagrid view cell value also by using this:
if (dataGridView1.Columns[e.ColumnIndex].Name == "companyName")
    {
        if (String.IsNullOrEmpty(e.FormattedValue.ToString()))
        {
            dataGridView1.Rows[e.RowIndex].ErrorText =
                "company Name must not be empty";
            e.Cancel = true;
        }
    }

Extracting text from webpage, processing with Perl/Python, then rebuilding the page with links added

I'm building a web app that processes the text in a web page, adds links to certain entities, then re-displays the page exactly as it was, but with some links added. My server-side code is in Perl
this:

 You could argue that the character in your examples are different, but the rule become besides complicated to follow. For model repeated parameters much used with Any type. This exemplar shell class Example(value: Option[String ] = None, otherValues: Any *) has different types, but still fight with the same problem
