[Boa Constr] Why are double-spaced lines necessary to make Frame Designer work?

[Warren P. <war...@ro...>]

I have noticed that if I delete the empty lines shown here from my Frame
object, Boa's form
designer stops working:

class wxFrame1(wxFrame):
    def _init_coll_menuBar1_Menus(self, parent):

        parent.Append(menu = self.menu2, title = 'FileMenu')

    def _init_utils(self):
        self.menuBar1 = wxMenuBar()

        self.menu1 = wxMenu(title = 'Test')

        self.menu2 = wxMenu(title = 'Test2')

        self._init_coll_menuBar1_Menus(self.menuBar1)


Is that by design?  If so, why?
