Calling `Sequence(elts, universe=...)` can be a good way to typecheck and
normalize a list of elements passed to a Sage function, but this sometimes
leads to hard to understand errors when one of the conversion fails. We
try to provide a better default error message (at the cost of losing part
of the backtrace until we have exception chaining).
