does #malli work with #babashka ? (just did a demo for my team and our infra human is curious)

Is there a reason :ref schemas just die for regex parsing? Why do they have to be surrounded by :maybe?

@ben.sless refs directly in sequence schemas are disallowed, rationale: https://github.com/metosin/malli/blob/master/src/malli/impl/regex.cljc#L1-L34

you can wrap anything in :schema to push it outside of the sequence.

Here's an example with hiccup, which is recursive:

(def Hiccup
  [:schema {:registry {"hiccup" [:orn
                                 [:node [:catn
                                         [:name keyword?]
                                         [:props [:? [:map-of keyword? any?]]]
                                         [:children [:* [:schema [:ref "hiccup"]]]]]]
                                 [:primitive [:orn
                                              [:nil nil?]
                                              [:boolean boolean?]
                                              [:number number?]
                                              [:text string?]]]]}}
   "hiccup"])

(def parse-hiccup (m/parser Hiccup))

I'll try. I got the parser working besides ref which I just hacked around for now

It works!

Updated the gist with working version, next step is a dynamic interpreter, followed by a compiler. It's pretty cool I can use the library to define new syntax. It extends itself
