Fun: Shooting yourself in the foot in D

[captaindet via Digitalmars-d]

as i just happened to have me mutilated, i couldn't resist (even though 
the example 'works' only with DMD-m64 bullets):


being forced to share your foot among parallel universes, it will surely 
find a stray bullet in one of them.


can you guess which toe is going to be blown off?

'''
version(DigitalMars)version(D_LP64){
	import std.stdio	: writeln;
	import core.atomic	: atomicOp;

	ulong toe0 = 2;
	shared ulong toe1 = 2;
	shared ulong toe2 = 2;
	shared ulong toe3 = 2;
	uint bullet1 = 1;
	int bullet2 = 1;
	ulong bullet3 = 1;

	toe0 -= 1;
	writeln( "toe0: ", toe0 );

	atomicOp!"-="( toe1, bullet1 );
	writeln( "toe1: ", toe1 );
	
	atomicOp!"-="( toe2, bullet2 );
	writeln( "toe2: ", toe2 );

	atomicOp!"-="( toe3, bullet3 );
	writeln( "toe3: ", toe3 );
}
