Unsolicited spelling correction: no 'i' in "deprecated".
What's going on? The docs say that it creates a new process. I simply
want to clear the console!
`system` directly prints its output, `executeShell` returns it in a
tuple with the status code. Maybe cls works by printing some specific
clear code. If so, you have to print the output of the command.
This works with `clear` on Linux which seems to behave similarly to
Windows' cls:
----
void main()
{
import std.stdio: write, writeln;
import std.process: executeShell;
import std.exception: enforce;
writeln("A");
auto r = executeShell("clear");
enforce(r.status == 0);
write(r.output);
writeln("B");
}

`wait(spawnShell(...))` is the other suggestion from `system`'s
deprecation message. It works for `clear`, too:
----
void main()
{
import std.stdio: writeln;
import std.process: spawnShell, wait;
writeln("A");
wait(spawnShell("clear"));
writeln("B");
}
