Nanatsu No Gengo Nanatsu No Sekai: Ruby,Io,Prolog,Scala,Erlang,Clojure,And Haskell (Tankobon Softcover)

The selection seems deliberate to cover a broad range of paradigms. I'm curious how the author decided which languages to include and what they hoped readers would take away from each.

Some chapters provided clear projects, while others felt dense. I wonder if others struggled with balancing theory and practice or if it made the learning more engaging.

The week-by-week format keeps things moving, but I wonder if a different pacing or order might have offered a different learning experience. Was this structure based on personal experience or research?
