Very cool! It looks like Rak has a lot of nice features.
I will say that getting this thing built took some digging. Could you please add install/build instructions to the README? As it is, I had to go sleuthing through your CI setup to figure it out. On Archlinux, here's what I did:
$ yay -S rakudo-bin
$ export PATH="/usr/share/perl6/site/bin:$PATH"
$ git clone https://github.com/lizmat/App-Rak
$ cd App-Rak
$ zef install .
$ export PATH="$HOME/.raku/bin:$PATH"
I realize features and an expressive language is your main goal, but I wanted to see what it looked like from a perf perspective:
$ git remote -v
origin git@github.com:rust-lang/rust (fetch)
origin git@github.com:rust-lang/rust (push)
$ git rev-parse HEAD

I'm not totally clear on what kind of filtering `rak` does by default, so I also ran a search on a single plain text file:
$ cd /dev/shm
$ curl -LO https://burntsushi.net/stuff/opensubtitles/2018/en/sixteenth.txt.gz
$ gunzip sixteenth.txt.gz
$ time rg 'Sherlock Holmes' sixteenth.txt -c
