considered harmful
     
        Edsger W. Dijkstra's note in the March 1968 "Communications of
        the ACM", "Goto Statement Considered Harmful", fired the first
        salvo in the structured programming wars.  Amusingly, the ACM
        considered the resulting acrimony sufficiently harmful that it
        will (by policy) no longer print an article taking so
        assertive a position against a coding practice.  In the
        ensuing decades, a large number of both serious papers and
        parodies have borne titles of the form "X considered Y".  The
        structured-programming wars eventually blew over with the
        realisation that both sides were wrong, but use of such titles
        has remained as a persistent minor in-joke.
