So then, something like this:

[StringArray.class]
' Gambas class file

Export
Inherits String[]

Public Sub Squash() As String[]

   Return Split(Super.Join(","), ",", Null, True) ' I like that code, Guianluigi; very slick.

End
[/StringArray.class]


[Main.module]
' Gambas module file

Public Sub Main()

   Dim myStringArray As StringArray

   myStringArray = ["risotto", "", "Pascualina", "focaccia"]
   myStringArray = myStringArray.Squash()
   For Each s As String In myStringArray
     Print s
   Next

End
[/Main.module]
