The training of programmers

Quote from Dijkstra[1]:

The training of programmers cannot be “easy”, for programming is, and will remain difficult. The point is that “learning the language” should, indeed, be a minimal affair, and the major attention should be given to mastering an orderly discipline how to use it.
