 Wow! I think of that as fairly basic, just buffers and simple
file manipulation (opening, reading, rewind), the kind of thing I do without
thinking (at least until I lose track of what's in which buffer) - unlike
say.

:.-2,.+5!sort

 Or

!}tr '[A-Za-z]' '[N-ZA-Mn-za-m]'

 Or using map which always makes me think too hard, or playing clever
games with the 9 cut buffers to shuffle text around which takes far too
much concentration to get right.
