We can either generate an IR that we simulate or we can do a tree walking interpreter.
IR
pro: we will have to generate this in the future anyway
pro: can be faster
con: will take longer
Tree walk
pro: very easy
con: we can't do much (if any) optimizations
con: we want to keep the interpreter in the system even when the compiler is working so making it too simple now would mean we have more work to do later.
