    More docs, example, and fixing the free page diagnostic function for mutable transactions

Happy that you’ve hit 1.0 on these changes. But when I try to build, with cargo clean; cargo build, I get:

Some errors have detailed explanations: E0423, E0425.
For more information about an error, try `rustc --explain E0423`.
error: could not compile `sanakirja-core`

Is this the same version that was pushed to crates.io? If not, how do I get those sources?

Looks like a bug in Pijul.

If you just want to get going, remove the second return statement.
