Hi all! My name is Daniel, I'm from Spain, this is my first contribution 
to Guix (well, to a discussion, actually)


I've seen this thread about Scala, and I would like to know more about 
the progress in bootstrapping in Scala. Scala (2) is my main language 
right now, but I want to try other purest options, Lisp being one of 
them, and also want to transition to Guix and contributing packages, 
eventually. I love what you, people, built.


Probably you know about this, but here is a link to an IRC channel about 
this: https://www.bootstrappable.org/projects/jvm-languages.html


It would be nice to have an exact dependency graph so that we can easily 
see the dead ends, and find the the most cost-effective solution. 
Probably translate old Scala code to a similar, already bootstrapped 
language would be a better option than building a compiler for Scala...


Thank you!

Dani.
