Preprocessor defines are not accessible between includes

[mealet]

👀 What Happened

I tried this code:

// lib.dn

#define PI 3.14

// main.dn

include "./lib.dn"

fn main() {
  println!("PI");
}

I expected to see this happen:
See output: 3.14

Instead, this happened:
Output is PI, so preprocessor didn't processed PI as a defined constant

Not necessary

Intended solution

Keep global mutable preprocessor context between include modules and re-process files if definitions are changed (very bad and unefficient way, need to figure out better solution)
