Re: Fun: Shooting yourself in the foot in 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 );
}

This is the best one so far! This is typical D: circumvent safety to enable you to shoot yourself in the foot.

As a result, it misses the foot, which has not grown yet. 2) From that link: http://www.toodarkpark.org/computers/humor/shoot-self-in-foot.html this one is good: Concurrent Euclid: You shoot yourself in somebody else's foot.

Accidentally compiling a massage into a gun is not a high priority bug. In order to become the safest language available, we should concentrate our effort implementing a nitrogen oxide detector (which handles all non-pathological examples of smoke).
