FWIW, a huge amount of work has been done to docs in the past year. There's even a dead-tree book available now (https://deeptext.media/perl6-at-a-glance/ ), with 3 more slated to release later this year.
I knew there was work in progress because I've made a similar comment in the past few months. I'm not in hurry which is perhaps in good alignment with Perl 6...A quick look at the book sample suggests it's not probably what I'd look for before starting a deep dive.
