[L2Ork-dev] Patch private abstractions

[Guillem Bartrina]

Here is the development branch in my repo:

https://git.purrdata.net/guillembartrina/purr-data/-/tree/feature_privateabstractions2

In the next few days I will read carefully everything you commented so 
far in this thread and I will start studying what can be easily included 
and figuring out how to fit the rest. I will also try to fix all the 
unclean techniques I've used.

Feel free to test the feature. Comments, thoughts, things that you would 
change, better implementations, bug reports, whatever, ... are welcome.
