Re: the list of languages made with racket [Hacker News]

The ycombinator post shows so many misunderstandings of the basic issue, it’s seriously sad. Here are some: 

1. S-expression syntax does not mean it’s the same semantics. 
2. The means of implementation in Racket are radically different from a lexer-parser approach. 
3. The nature of languages ranges from 
	— stand-alone languages with ugly syntax (example: datalog)
	— #lang stand-alone DSLs (config, scribble)
	— #lang language mixins (s-expr, 2d)
	— embedded DSLs with mostly coarse-grained interactions with Racket (redex)
	— embedded DSLs with fine-grained interaction with Racket (the language of class syntax; syntax-parse: the pattern and templated languages, which interact via syn-pattern vars)
	All of these are available via libraries. And I am almost sure I am forgetting some classes of languages here. 

I suspect that if we collected the languages in just these categories, we’d easily find over a hundred if not several hundred in both our code base as well as external code repos. 

Thanks for taking up the battle against this lack of knowledge out there — Matthias
