Yes, I've had to learn this one the hard way, too. And more than once, I have to admit.

When I was working on Mathematica, a lot of effort was put in to making examples for each doc page. One example (that I didn't work on) picked at random: https://reference.wolfram.com/language/ref/RandomVariate.htm...

Mnesia is _not_ the storage layer for messages (except for delayed messages).

Mnesia stores vhosts, users, permissions, queue definitions and more. This is being transitioned to Khepri, which improves a lot of things (maybe most importantly netsplits) but not directly message speeds.

Yes, a stream queue type [0] is available where you can set retention, and replay messages.

Continuous System Simulation by Cellier/Kofman [0]. The focus is mainly on Modelica, but analog circuits are a "special case" of this.

Yes came to say this. The Erlang VM is about lightweight processes and message passing.

Yes, they built a platform Cello [0] that would allow for that if I remember correctly
