Yeah, exactly. You're correct that it's not *impossible* or even *actually difficult*, it's just messy and annoying and that's not enough improvement over my current situation, whereas Lazy is cleaner.

Don't worry, I was never under the impression it was *impossible* even when I started (long before 1.70) I was just expecting to need a third party crate to make this tidy and now probably I won't.

There's a lot more work to do to properly approach the vision from the Java API but in a nicer language, but I think I'm closing on the point where it's a useful alternative to tools like the Unix "basic calculator" bc or the typical GUI calculator on your desktop OS.
