Declaring Global Values
Global values can be declared with the val
keyword.
This is sometimes useful to provide clarity as opposed to defining functions for constants.
val min_members = 1
val max_members = 20
All initializations for global values occur before the main
function is ran.
If you're writing low-level code then it might be useful to receieve the raw pointer of a global value and mutate it at runtime.
use std:io
use std:ptr
val count = 0
fn main =
let ptr = builtin:val_to_ref count in
do ptr:write ptr 5
then io:println count
