Guillaume,

you have not been lisping enough :-)

I think, and that's the way it is implemented, 
that SET should return the previous value.
I might be useful and nice:

{
  # lock window size
  my $oldvalue = $win->resizable(0);
  .... (do stuff) ......
  $win->resizable($oldvalue);
}

and since you use:

$value = $win->resizable;

to GET it would be inconsistent not to return something
when you do a SET with the same function.
