The simplest cases are also the most common, IME. But yes, I'd like to
expand it to work in a few more cases and be less insane (I'd rather
not interpret printed output as Python code).

Yeah. I don't know of any solution to that either. Even if pure-python
code generates that repr, it isn't possible to even replace the repr
with a sorted dict-repr in any sane way, because %r doesn't defer to
repr. It's just an intractible case. Nothing at all mentioned in this
thread would work there.

And I never called it easy, by the way.
