> Elixir, I still had to know my whole call chain to know what I could do with my incoming parameters. The more call sites, the more mental context.
but the call chain doesn't have to be long, i.e. it could be just 2 or 3 places; that fits inside my head. less is more
Sure, but it stops being that with multiple teams stepping in the same codebase as business needs expand. You revisit an area of code to find Sam in the billing department (who you don't know) interjected something or other and now there can be assumptions about the shape of data that were different than before. For us, it was data report shapes.
Elixir is amazing when the system fits in your head.
