Ok, is that what is called « intelligent phones » ?

It doesn't exclude having your own buffer system either. What you need to 
do, is to use polymorphism : a common clipboard protocol, for two 
different kinds of clipboards. DesireData has that in its implementation, 
and it temporarily replaces the global clipboard variable in order to 
switch to a private clipboard because Ctrl+d is implemented as Ctrl+c 
Ctrl+v yet shouldn't modify any normally visible clipboard.

class_new Clipboard {Observable Thing}
class_new Clipboard1 {Clipboard}
class_new Clipboard2 {Clipboard}

def Clipboard init   {{value ""}} {super; $self value= $value}

def Clipboard1 value= {value} {clipboard clear; clipboard append $value; $self changed}
def Clipboard1 << {value}     {                 clipboard append $value; $self changed}
def Clipboard1 value {} {clipboard get}

def Clipboard2 value= {value} {set    @value $value; $self changed}
def Clipboard2 << {value}     {append @value $value; $self changed}
def Clipboard2 value {} {return $@value}

if {$tk} {
   set clipboard [Clipboard1 new]
} else {
   set clipboard [Clipboard2 new]
}

def Canvas do_duplicate {offset} {
         global clipboard
         set backup $clipboard
         set clipboard [Clipboard2 new]
         $self copy
         $self do_paste $offset
         $clipboard delete
         set clipboard $backup
}
