Equations are immutable, so you should *not* be changing the internal
state of equations. Actually _left and _right aren't private, they are just
"you should not mess with them", by convention. If they were private
they would be __left and __right. In fact, they should be changed to
be private.
So you like the suggestion to do
b.change_right(...)
and
b.change_left(...)
each of which returns a new equation?
Bobby and I don't really like
sage: a.rhs.expand()
since it's a hackish abuse of notation and it is confusing to read.
It's clever though (which is not good).
