Luna c4401dc8cf moving to the virtual machine part of the book, pt 1 
the java part would still fuck me up since it lies on OOP stuff
that zig doesnt provide, so i'm skipping towards the C part of the book
which will hopefully be more understandable from a zig perspective.

Luna 7ce0565de7 add basics of a handwritten parser 
hell yeah i'm going down that path

handwritten one, but oh well, such is life
