A toy implementation of Landin's ISWIM language. (2018)

Was rewatching a Strangeloop video from 2015 by Philip Wadler (well worth the watch) and that the only 'discovered' (vs invented) language I did know know is ISWIM[0].

Seems a very interesting language which is trivial to implement, like Lisp (well, some basic version of it). Not as trivial as Forth, but then again, Forth is not in the same category of languages besides that it's also old.

There is something more recent [1], however I didn't try it yet and it says 'help writing interpreters' so i'm not sure if it actually works / does anything.
