M-% +++ ret ++ + ret !
Since addition is a commutative operation you could have written a = 3 +
c++;
What is the operator precedence of inc and binary +?
Here's an example of something even more perverse:
char*f="char*f=%c%s%c;main()
{printf(f,34,f,34,10);}%c";
main(){printf(f,34,f,34,10);}
or, more on topic:
((lambda (x)
(list x (list (quote quote) x)))
(quote
(lambda (x)
(list x (list (quote quote) x)))))
Both programs print themselves and were called quines by Douglas
Hofstadter, after the logician:
