One use of self-modifying code that still survives is total balls-to-the-wall
block operations, such as BitBlts. There was a discussion of hardware
graphics coprocessors where someone (maybe Henry Spencer, as the leading
opponent of the beasts) brought this up. I have not seen such code myself,
but it involved generating the BitBlt subroutine optimised for the operation
desired on the fly and then executing it.
