Macro si_trace_print::p

macro_rules! p {
    (
        $($args:tt)*
    ) => { ... };
}

println!

For completeness, wrap println!.

use si_trace_print::{pfn, pfx};
use si_trace_print::p;
fn func1() {
    p!("hello");
}
fn main() {
    pfn!();
    func1();
    pfx!();
}

prints

→main:
hello
←main:
