What about the rule: there are two object classes, one which covers data 
series and everything else which is saved in the datafile (as opposed to 
the session file), and the remaining stuff which gretl does not save in 
a datafile. (Don't know how gretl currently treats or should treat 
scalars and strings.)  '--preserve' would apply to all objects in the 
second class.

I agree; for example for the py4gretl functions it would have been nice 
if it had been possible to define and/or check the existing lists 
visually before calling the function package. (The list definition 
dialog from within the function package is very nice, couldn't that be 
promoted to a more broadly available dialog?)
