Append Source To Binary

Is their a way to append the source code of an executable to the file itself such that the file is still executable?

For example let's take a simple program like yes from busybox. How might I append the code in a way to the binary. Again this is a simple example, I would like to be able to do such for for a multiple file example that allows you to retrieve the code.

#include "libbb.h"

int yes_main(int argc, char **argv) MAIN_EXTERNALLY_VISIBLE;
int yes_main(int argc UNUSED_PARAM, char **argv)
{
    char **pp;

    argv[0] = (char*)"y";
    if (argv[1])
        ++argv;

    do {
        pp = argv;
        while (1) {
            fputs(*pp, stdout);
            if (!*++pp)
                break;
            putchar(' ');
        }
    } while (putchar('\n') != EOF);
