The cora programming language
Inspired by scheme, shen, femtolisp and many more...
closure can be printed readably
(lambda (a) 3 (b . 5) (c . 7)) as femtolisp
kernel lambda
Minimal special forms:
- quote
- lambda
- if
- do
set is a function rather than special form.
let is a macro.
(let a 3 b 5 ...)
proper tail call
proper tail call, as scheme does.
partial apply
pattern match
(match (cons 1 2)
(cons a b) a)The func macro
(func map
f [] => []
f [x . y] => [x . (map f y)])Nowadays any cats and dogs write their own programming languages, mostly sucks. Many of them are too small to be even a finished toy, many lack features, worsely, many choose the wrong features.
However, it's still an important practice for a true lisp hacker to keep inventing his own one, adapting the language to his own taste.
Among the most important features, lisp1, of course. Then comes proper tail call and partial apply, for functional programming goodness. Keep the kernel language miminal is also important, I think.
