Feature or enhancement

What's better than a pretty print? A colorful pretty print!
By extracting the syntax highlighting code from the REPL, we can get the same colorization for literals in the pprint module.

I had Codex make me an example, and it works pretty nicely:

This will likely conflict with the PEP 813 reference implementation, so I'm going to keep the PR as a draft for now.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere

    This is a duplicate of #145217, no?

    Yes, I think the issue is a duplicate, but my PR has stalled so I welcome a new attempt!

    Do have a read through the comments on my PR and check the blockers are addressed or not relevant in your approach (I've not looked yet).

    Ah, I thought the idea sounded familiar! I'll take a look at your PR.

    Let's think about this in relation to the PEP 813 work.

    Yeah, I don't plan on marking the PR as non-draft until a decision is made on PEP 813.
