Line 4:
# This makes dependencies explicit.
# This leads to [http://www.haskell.org/haskellwiki/Referential_transparency referential transparency] -- given the same arguments, a piece of code will always behave identically.
# Coding is '''compositional''' -- any two pieces of code with a matching 'interface', as specified by function domains, can be combined, because no hidden side-effects can intervene. (See [httphttps://www.stanfordthocp.edunet/classbiographies/cs242papers/readings/backusbackus_turingaward_lecture.pdf ''Can Programming Be Liberated from the von Neumann Style? A Functional Style and Its Algebra of Programs''] by John Backus, 1977 Turing Award Lecture).
# It's easy to '''refactor''' similar pieces of code, because any subexpression can be replaced by a variable bound at the outside.
