It is intended to combine the elegance of the\n(point-free) \"concatenation is composition\" model with the elegance of\nLisp-like languages.\n\n→ Try koneko in your browser with the JavaScript\nREPL.\n\nNB: use whitespace to separate tokens since \"special\" characters like\n+ and ( are not delimiters but valid parts of identifiers.\n\nDetails:\n→ Language Features,\n→ Ident(ifiers) \u0026 Quoting\n\nNB: all data types are immutable.\n\nNB: nil and #f are falsy, everything else is truthy.\n\nDetails:\n→ Primitive Data Types,\n→ Pairs, Lists \u0026 Dicts,\n→ Records\n\nNB: since purely concatenative programs contain no free variables,\nalmost any \"subexpression\" can be \"factored out\" simply by giving it a\nname.\n\nDetails:\n→ Functions,\n→ Multi(method)s\n\nDetails:\n→ Primitives, Builtins \u0026 Prelude,\n→ Prelude: Syntax Highlighted Source,\n→ Prelude: Function Index\n\nDetails:\n→ Syntactic Sugar\n\n→ 01: Language Features,\n\n→ 02: Ident(ifiers) \u0026 Quoting,\n\n→ 03: Primitive Data Types,\n\n→ 04: Pairs, Lists \u0026 Dicts,\n\n→ 05: Functions,\n\n→ 06: Multi(method)s,\n\n→ 07: Records,\n\n→ 08: Syntactic Sugar,\n\n→ 09: Primitives, Builtins \u0026 Prelude,\n\n→ 10: Standard Library,\n\n→ 11: Possible Future Extensions\n\n→ Syntax Highlighted Source,\n→ Function Index\n\n→ More Examples\n\nLike Python (\u0026 Haskell), koneko supports \"doctests\": executable pieces\nof documentation that look like interactive REPL sessions.  Doctests\nmake it easy to write user tutorials, documentation, and regression\ntests at the same time and confirm that examples in documentation are\ncorrect and up to date.\n\nNB: this README, the Language Reference, and koneko's Prelude \u0026\nStandard Library are full of doctests.\n\nLets look at an example, mylib.knk:\n\nWe run koneko with the --doctest option (in this case also with -v\nfor verbosity) to execute the tests in a koneko -- or markdown --\nfile:\n\nNB: for :mylib use to be able to load the mylib.knk file we need\nto add the current directory to KONEKOPATH.\n\nSee (Build) Requirements.\n\n...
