Parsing Clojure namespace forms using Raku grammars

One day, I started wondering if it would be possible to parse Clojure namespace forms and generate a dependency graph of the various namespaces used in a real-world Clojure project. While that was the original motivation, I ended up down the Raku grammar rabbit hole, and had an enjoyable time learning how to use them. I'm glad you're joining me in reliving that journey.

Background

#!/usr/bin/env raku

use v6.d;
#use Grammar::Tracer;

grammar RealisticNs {
    token TOP { <realistic-ns> }

    token realistic-ns { <lparen>
                           <ns-keyword> <.ws> <ns-name> <.ws>

grammar EmptyLispForm {
    token TOP { <lparen> <rparen> }

    token lparen { '(' }
    token rparen { ')' }
