Hi Vladimir,

This looks pretty similar as a concept to the raw prototype I've put
together and posted this evening:

https://lists.gnu.org/archive/html/emacs-devel/2020-05/msg01034.html

I do not have the prefix for importing but is something I wanted to add.

I'm learning also here that Scheme works on bindings too, good to be
ignorant!! :)  Now I've very curios to see how different is from what I
came up with.

  Andrea
