This is interesting.
I’d very much like to see a code formatter do that kind of thing; currently formatters are pretty much inflexible, which makes getting structure out of a formatted code sometimes hard.
Both objects desugar to a sequence of segments (lines).
The result is that you can freely mix expression/assignment blocks & statements. Things like switch-case blocks & macro tables are suddenly trivial to format in 2d.
Because comments are handled as right floating, all comments nicely align.
I vibe coded the base layer in an hour. I'm using with autogenerated code, so output is manually coded based on my input. The tricky bit would be "discovering" tables & block. I'd jus use a combo of an LSP and direct observation of sequential statements.
