Will this be covered in the Perl 6 book

No, the book focuses on using Perl 6, not on the trickiness of implementing it.

or could you point me to some other documentation on how this works

For example S06 talks about operator overloading and defining new operators, S13 does that too.

Perl 6 - links to (nearly) everything that is Perl 6.
