The pseudo-XML is a language I made called CSTML: https://docs.bablr.org/guides/cstml. I looked back and I don't see any unclosed tags, nor anything that would be an unclosed tag in XML either.

I'm sure you could abuse a git `tree` to squish in the extra data, but my point was just that you'd have to because a directory doesn't have a name that's separate from the name its parent uses to point to it. An AST node has both a name that its parent uses to point to it and an named identity e.g.:

``` <BinaryExpression> left: <Number '2' /> op: <'+'> right: <Number '2' /> </> ```

So my point is that to fit this into git you'd have to do something funky like make a folder called `left_Number`, and my question about this is the same question as I have in the first place about creating a folder on disk named `Number` whose contents are only the digit `2`. Since every existing tool will present the information as overwhelming amounts of nonsense compared to what users are used to seeing, has any compatibility at all been created? What was the point?

I also see the need to check out files as being an aspect of Git that relates purely to its integration with editors through flat text files. But if git was a more of a database than a filesystem then it's fair to assume that you'd prefer to integrate database access directly into the IDE.
