• names -> de Bruijn -> names
Might fail, but if it doesn't it will give you back the same process.
• de Bruijn -> names -> de Bruijn
Might give you back a different process, but it will always succeed.

What do you mean when you say 'process' here?

Sorry, just any kind of term, it's just that I'm doing pi calculus

Oh, right, np! Why does converting back to names give a different term/process?

Going from de Bruin to name you lose information: names might be shadowed. However, you are guaranteed to build a well-scoped process.

Ahh right - is it possible to handle this in the conversion? Like, I try to handle shadowing in my core-to-surface language translation pass (core language uses de Bruijn, surface language uses names). I could be doing something wrong though. 😅

If you are willing to generate fresh names, then absolutely. In my case, if the user provides a well-scoped process, they get the exact well-scoped process back. Though maybe I should not attempt to do this and do the disambiguation?

Ahh cool! Yeah, fresh names is how I am doing it - I keep hints around of the original names to do it in a best-effort way.
