Clearly you don't know what you talk about.

Which is more readable (taken from a program I develop) :

Your proposal (note if one use an editor that has wrapping on one will
screw up the code as it will put this _one_ line on several)

    Button_Callback.Connect (Gui_Result.Practise_More_Button, "clicked", Button_Callback.To_Marshaller (On_Practise_More_Button_Clicked'Access))

As you can see it is almost impossible to fit it within the horisontal
viewport of the editor, and it is not an exception.

Ada way with ;

     Button_Callback.Connect (Gui_Result.Practise_More_Button, 
                              "clicked", 
                              Button_Callback.To_Marshaller 
                                 (On_Practise_More_Button_Clicked'Access));

Of course if you talk about Fortran 77 this cannot be coded and the
variable would have really meaningful names like:

   PRXMBTN -- Practise_More_Button

FORTRAN 77 is probably one of the worser languages (apart from Perl and
flavours) to make readable code in because of the limitations on the
number of characters one can use for a variable name and that hopelessly
idiotic automatic type casting which produces loads and loads of errors
that are very hard to find. I really hope that F77 isn't used in any
safety-critical systems.
