I don't quite understand why it's necessary to wrap every data type into
a GiNaC class (the same applies to lst, actually). Such wrapping results
in a nonsense like

{x, y} + {x, y}
2*{x, y}

and doesn't seem to do anything useful.

Exactly. I think "everything is an expression" is a bad idea.

Best regards,
