None of the overloads of kill are callable using argument types:

[BoQsc via Digitalmars-d-learn]

I'm trying to kill my own process, but I'm being unsuccessful at 
the compilation of the program. It seems that neither getpid nor 
thisProcessID returns a correct type value for the kill function.

HelloWorld.d(24): Error: none of the overloads of kill are 
callable using argument types (int), candidates are:
C:\D\dmd2\windows\bin\..\..\src\phobos\std\process.d(2327):       
 std.process.kill(Pid pid)
C:\D\dmd2\windows\bin\..\..\src\phobos\std\process.d(2338):       
 std.process.kill(Pid pid, int codeOrSignal)
