Readln function is activated before the writeln("test"):

-----
import std.stdio;

void main() {
	
	writeln("test");
	
	string s = readln;
	
	writeln(s);
}

It's a problem related to flushing. The `writeln("test")` is not flushing its output before the readln happens.

Thanks.

import std.stdio;

void main() {
	
	writeln("test");

	stdout.flush;
	
	string s = readln;
	
	writeln(s);
}
