At some point {{{E.a_invariants()}}} was changed to return a 5-tuple
instead of a list of 5 numbers. I have no idea why. But this means that:
{{{
sage: E = EllipticCurve([1..5])
sage: EllipticCurve(E.a_invariants())
TypeError: invalid input to EllipticCurve constructor
}}}
Ugh. Fix this, i.e., make the constructor take a tuple or a list.
