and yet it was Dijkstra who wrote:

"...whereas machines must be able to execute programs (without
understanding them), people must be able to understand them (without
executing them). These two activities are so utterly disconnected --
the one can take place without the other..."

so perhaps he understood something about use of metaphor.
