Just like Erlang, my favourite feature of picolisp is the built-in database format: https://software-lab.de/doc/ref.html#dbase

Discloure: I am a DBA. And a Lisp addict.

EDIT: This not supposed to be a reply.

Cool! Most DBA's I know tend to stay on the side of what is popular like Java. Do you use Lisp at work? If so, any pushback?

Tons of pushback. But at the end of the day, the people who moan don't manage the databases.

I stick with that is available in centos+EPEL, which includes sbcl, and use ODBC for most of my work.

The common tooling for open source databases is varied. A lot of what makes mariadb and postgresql happen is c, shell scripts and perl. A lot of 3rd party tools are still php.

pgloader is a common lisp tool, and very useful.

Rather than more, it might be a symmetry relationship where picolisp seems to try to give a simple small lisp for giant computers, whereas ulisp tries to provide a giant lisp for small computers.

Both look like a lot of fun.
