Perl Style: Data-Oriented Programming

  • Data structures are more important than code.
  • Rob Pike says: `Data dominates. If you’ve chosen the right data structures and organized things well, the algorithms will almost always be self-evident. Data structures, not algorithms, are central to programming. (See Brooks p. 102.)’
  • Capture regularity with data, irregularity with code. (Kernighan)
  • If you see similar functionality in two places, unify it. That is called a `subroutine’.
  • Consider making a hash of function pointers to represent a state table or switch statement.
