"comptime":
```
comptime std = module {
⠀⠀comptime puts = extern fn puts(msg: *char) -> i32;
⠀⠀comptime compute = () -> i32 {
⠀⠀⠀⠀comptime x = /*some heavy computation, that happens at compile-time*/;
⠀⠀⠀⠀let y = 3;
⠀⠀⠀⠀x + y
⠀⠀};
};
comptime main = fn () -> i32 std::puts(c"Hello, World!");
```
"symbol":
```
symbol std = module {
⠀⠀symbol puts = extern fn puts(msg: *char) -> i32;
⠀⠀symbol compute = () -> i32 {
⠀⠀⠀⠀symbol x = /*some heavy computation, that happens at compile-time*/;
⠀⠀⠀⠀let y = 3;
⠀⠀⠀⠀x + y
⠀⠀};
};
symbol main = fn () -> i32 std::puts(c"Hello, World!");
```
"const":
```
const std = module {
⠀⠀const puts = extern fn puts(msg: *char) -> i32;
⠀⠀const compute = () -> i32 {
⠀⠀⠀⠀const x = /*some heavy computation, that happens at compile-time*/;
⠀⠀⠀⠀let y = 3; // Note: This is immutable, but run-time
⠀⠀⠀⠀x + y
⠀⠀};
};
const main = fn () -> i32 std::puts(c"Hello, World!");
```
Nothing:
```
std = module {
⠀⠀puts = extern fn puts(msg: *char) -> i32;
⠀⠀compute = () -> i32 {
⠀⠀⠀⠀x = /*some heavy computation, that happens at compile-time*/;
⠀⠀⠀⠀let y = 3;
⠀⠀⠀⠀x + y
⠀⠀};
};
main = fn () -> i32 std::puts(c"Hello, World!");
```
"::":
```
std :: module {
⠀⠀puts :: extern fn puts(msg: *char) -> i32;
⠀⠀compute :: () -> i32 {
⠀⠀⠀⠀x :: /*some heavy computation, that happens at compile-time*/;
⠀⠀⠀⠀let y = 3;
⠀⠀⠀⠀x + y
⠀⠀};
};
main :: fn () -> i32 std::puts(c"Hello, World!");
