Square brackets around the function name

Question

I am trying to understand delegates at the moment and came across the following snippet:

Function [Select](ByVal numbers As List(Of Integer), ByVal filter As Filter) As List(Of Integer)
    Dim result As New List(Of Integer)
    For Each number In numbers
        ' call delegate
        If filter(number) = True Then
            result.Add(number)
        End If
    Next
    Return result
End Function

I was looking for an explanation, but all I could find was this , but that didn't help me understand the snippet I found. Can someone help me figure out what the square brackets are for [Select]?
