This was the basis of an excellent entry [0] in the 2007 Underhanded C Contest. It had a correct implementation of the RC4 encryption algorithm, except it used the XOR swap, so on average one byte of the pseudorandom state was zeroed every

Google Maps launched in 2005; if it works in India now, then it took at most 11 years more to get it working in India than in the US. That's not that long. Self-driving cars are more complex, but it'll happen eventually.

The distinction between program and data is not a sharp one, since f(x) = apply(<f, x>) = eval_x(f) (where eval_x takes the description of some program f and runs it on the constant input x). You can use this equivalence to compute

"What is 6+1*0-2/2?" memes/threads on Facebook have taught me that infix math notation is more or less completely unfamiliar to the general population. At least sexprs are fully parenthesized.
