Description
Write a program A which when run emits to STDOUT a program B in the same language. Program B when run should then emit the source of A.
The source of A and B must not be identical–that is, A alone must not be a quine. Trailing whitespace is ignored in this comparison, and in the comparison of B’s output and A.
