Declarative programming (todo)

Todo

• I like a declarative style

  • describe what you need; not how to implement (the details)

• Makefiles are a good example

• Argparse (vs loop over argv) is a second example

Note

CCastle: blog: “(1) declare what you need”. Declarative style programing. Eg loop over Argv vs argparse, makefiles

Cyclic woods (todo)

Todo

Generalise and abstract the famous tree-structure and allow cycles

E.g. a AST is tree with “cycles”: Each var is defined and used. Use “href” alike
