1. It's not that trivial in a "script" language

2. It's exactly as difficult in a "script" languages as in pd. (pd isn't 
as special as we may believe it is)

in practice, a pd canvas may have all of those persistent states which are 
not part of the canvas' contents per se:

   (x,y) origin of the canvas window
   (x,y) size of the canvas window
   (x,y) size of the gop
   (x,y) margin for gop
   (x1,y1,x2,y2) range for graphing
   font size
   gop flag
   gop rectangle flag

and in practice, IEMGUI has been integrated to pd itself 5 years ago, 
everybody takes them for granted, and they're full of violations of 2.6.2; 
it could even be argued that the nature and the goal of IEMGUI is to 
violate 2.6.2.

the creation time would be also important in the case of the first 
solution. (i don't see why it wouldn't.)

this can be made in a semi-automatic way, e.g. an item in the Edit menu 
which would recreate all objects as if the patch had been reloaded from a 
file. This is roughly equivalent to Ctrl+A Ctrl+X Ctrl+V, but now the 
second solution is different in the sense that Ctrl+V would have to 
figure out namespaces in order to create its objects properly (!!).
