Replying to [comment:6 sluther]:
All of the `simplify_foo()` functions except `simplify_radical()` could
benefit from it. There are only a small number of subexpressions that can
be simplified by `simplify_real()`, and I think only `simplify_radical()`
will "simplify" out those subexpressions making `simplify_real()`
redundant.
The `simplify_radical()` method will change the expression `sqrt(x^2)` to
either `x` or `-x` "consistently but arbitrarily.". This is not really a
simplification, since it gives the wrong answer in the default case, so
beware using `simplify_full()`. All of the rest could be combined with
`simplify_real()` in some way.
