You need then `stdin.readf!" %c"(x);`
It worked for me with `echo "123" | .\app.exe`

But this is the simplest example. Support for different UTF 
symbols could require more work

id probably just do

```d
import std;

void main(){
	foreach(dchar c;stdin.byLineCopy.map!(a=>a.array).joiner){
		c.writeln;
	}
}
```
Everything will be fairly hacky
