Comment (by kcrisman):
You need to do `\left|x\\right|`.

I'm not sure about all the stuff in the doc and the code, but I think that
some of the doc is doing the code and vice versa? For instance,
{{{
# Forget all assumptions
}}}
but you don't do that in the code. And the corresponding part in the doc
seems to imply that in order to use `simplify_real` you have to assume
variables are real... I may be misunderstanding something here. I think
this could be a good way to solve the issue at hand.
My question is how this will interact with the other simplifications. I
seem to recall that in some of the more controversial (e.g.
`radcan`-related) simplifications we do, part of the issue is whether the
variable is real... that recollection may be outdated. Anyway, I could
imagine that `simplify_foo` simplified differently whether one was real or
complex, though I hesitate to add `simplify_foo_real` for all `foo`!
