Hi Matthias, (or anyone else who is available to answer :)) I'm trying to get my head around the range of possible languages in Racket.
You got me thinking how many languages seem to have embedded little languages. I was wondering how they fit into your categories of languages? 3.

Kind regards, Stephen PS I need to add minipascal to https://github.com/racket/racket-lang-org/pull/89 On Sat, Feb 23, 2019 at 11:08 PM Matthias Felleisen <[email protected]> wrote: > > > The ycombinator post shows so many misunderstandings of the basic issue, > it’s seriously sad.
