The problem, of course, is that there are wildly different definitions/thresholds for clever. Dijkstra's comment was made when assembly language was widespread, and I suspect that his idea of "clever" involved the various ways people can famously make assembly language unreadable. In the introduction to "A Discipline of Programming," he asks if advanced language features belong to the solution set or the problem set, but he doesn't define "advanced," so I can't say where he put the threshold.
