On FOSDEM and Guix Days we were discussing an absence of REPL in Arei/Ares.
One of the concerns was: with in-buffer evaluation workflow in contrast to REPL/jupyter notebook we don't see the correspondence between an expression and the value of its evaluation. It can negatively impact user experience and also makes Arei harder for learning/exploring.
I mentioned that this can be addressed by eval-and-print-to-comment.
Here is the demo of how it works:
