 * A Retargetable C Compiler: Design and Implementation by Christopher W. Fraser and David R. Hanson - sometimes looked at this as a reference to figure stuff out. Very helpful resource on compiler construction, the way it's written reads more like documentation but you use what you have.
 * https://github.com/JoshuaManton/sif - looked at this as a reference from time to time, author seems like a Jonathan Blow fan so it was a good resource informed by similar resources as I used.
 * https://github.com/c3lang/c3c - I sometimes looked at C3 compiler as a reference, the author also let me use his big int library he wrote sometime in the past! Thanks a lot!
+* https://go.dev/blog/constants - article on golang type system, untyped types, constants that kind of stuff.
