Very minor: should we also allow m isa Module here in case people interpolate a module into the AST?

The previous version of the code parenthesized Modules, but I'm not sure why. I guess we'd need $ to be super accurate about it.

Good point, it would be nice to generally show the difference between purely symbolic ASTs vs ASTs which have "unusual" objects interpolated into them. Especially for things like modules which show the same way as symbols.

@KristofferC what's the procedure to do a complex backport? PR against the backports branch?

Yes, a PR against the backports branch should be fine. Thanks for handling this!! ❤️

Can also just push directly to the backports branch.
