db-with is a function, just not in the docs, because Datalevin is not an immutable db, so there’s no such thing as “DB as a value”. The DB is going to mutate.

so db-with will return the mutated db, but the old db is mutated as well, you won’t have an intact old db.

0.6.17 will have a function called tx-data->simulated-report that will simulate a transaction, but won’t persist the changes, which might be useful for some.

Will appreciate it. Thanks for the help!

PR available, put it as first badge but we can move it if you like.
