Oops! Good catch! I'm so embarrased by my oversight. Here you go: $ cat rdmdFOREVER.d import std.process; void main() { system("rdmd rdmdhello.d"); system("rdmd rdmdFOREVER.d"); } $ rdmd rdmdFOREVER.d Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world Hello world [snipped]

Oops! Good catch! I'm so embarrased by my oversight. Here you go: $ cat rdmdFOREVER.d import std.process; void main() { system("rdmd rdmdhello.d"); system("rdmd rdmdFOREVER.d"); } $ rdmd rdmdFOREVER.d Hello world Hello world Hello world

And just for the hell of it: $ cat rdmdFOREVERish.d import std.file; import std.process; void main() { system("rdmd rdmdhello.d"); if(!exists("KILL-FOREVERish-NOW")) system("rdmd rdmdFOREVERish.d"); } But you don't expect to kill it MANUALLY, without even using rdmd once, do you? So here: $ cat killFOREVERish.d import std.conv; import std.file; import std.process; import std.stdio; void main(string[] args) { int theFinalCountdown = 5; // DOOT! DO DO DOOOO DOOT!! if(args.length > 1) { try theFinalCountdown = to!int(args[1]); catch(Throwable e){} } if(theFinalCountdown <= 0) { writeln("DIE, FOREVER! DEAD DEAD DEAD!!"); mkdir("KILL-FOREVERish-NOW"); } else { writeln(theFinalCountdown); --theFinalCountdown; system("rdmd killFOREVERish.d "~to!string(theFinalCountdown)); } }

kill your program, did you?

I'll just have to make one that submits each result to the NG automatically! . . . . . . . (No, I'm not actually going to do that...)
