kill and thisProcessID

[Nordlöw]

I have a process that shall suspend itself using SIGTSTP or 
SIGSTOP.

My current plan is
    import std.process: thisProcessID, kill, Pid;
    import core.sys.posix.signal: SIGKILL, SIGSTOP, SIGTSTP;
    const thisPid = thisProcessID;
    // some call to kill()

but kill() needs a `Pid`

so

    kill(thisPid, SIGTSTP);

fails and constructing Pid cannot be done because

    kill(new Pid(thisPid), SIGTSTP);

errors as

    Error: class std.process.Pid member this is not accessible

What to do?
