Recursion while using QTreeWidgetItem.__lt__

class RepoBranchInfoTreeItem(QTreeWidgetItem):

   def __lt__(self, other: 'QTreeWidgetItem') -> bool:
   col = self.treeWidget().sortColumn()
   if col != 1:
    # regular sorting
    return bool( QTreeWidgetItem.__lt__(self, other) )

   colTextSelf = self.text(col)

      # natural number sorting if we can
      return extractInt(colTextSelf) < extractInt(colTextOther)

 # regular sort strategy will compare strings and place all number starting strings before others
 return bool( super().__lt__(other) )
