Self-recompiling C++ program

Just an idea of how one can write a program that re-compiles itself ad infinitum

Running

g++ main.cc -o main.run
./main.run

# 'head -64' is useful when the program has been left running for too long
ps aux | grep "/tmp/x.run" | head -64 | awk '{print $2}' | xargs kill -9
