The following is not one of the most concise Quine self-reproducing
expression. Yet, it is a favorite of mine: quoteless with a Godelian
body-genes pattern,
({&a.,":)40 123 38 97 46 44 34 58 41
and,
128!:2~'128!:2~' NB. Try it only on a fresh session!
is a concise, J Windows-crashing/PocketPC-hanging, self-executing expression
that, for some reason, I find more appealing than,
$: 0 NB. | stack error
A variation of the above is a Windows-hanging/PocketPC-hanging-unstoppable
expression,
($:+$:)0
(I am not suggesting that J should be able to deal with these expressions.)
