[Gambas-user] Request for comments about a language change

[Jussi Lahtinen]

Oh, of course all enumerable classes, I was thinking command ENUM...
I try to think whether there could be situation where this would hide error
in code.
If for some error you pass Null object to this:

Public Function CountLargeObjects(hArrayOfObjects As Object[]) As Integer

  Dim hObject As Object, iCount As Integer

  For Each hObject In hArrayOfObjects
    If hObject.Size > 100 Then
    Inc iCount
    Endif
  Next

  Return iCount

End


Then it may be harder to catch.
But I don't think that is big deal, if this change has some great
potential..?
