This is certainly a bug:
sage: a = sqrt(-3)
sage: a
sqrt(-3)
sage: a.conjugate()
sqrt(-3)
sage: bool(a==a.conjugate())
True
But I have no idea where to look for it, since symbolic expressions
are a mystery to me!

And the determinant of the action of a
In number theory it is very useful to have this norm-alisation, as
well as the square root one also called abs. It's a special case of
the algebraic concept of norm(a) = product of conjugates of a.
If this was really a problem to non-number-theorists, we could
possibly live with it (possibly by
