Case statements in sane languages

    How do you do this in ADA?

	switch(n) {
	  case 0:
	    count++;
	  case 1:
	    ocount++;
	  case 2:
	    printf("%d %d\n",count,ocount);
	    break;
	  default:
	    printf("unknown n\n");
	    break;
	}

    See how I left out the breaks on purpose.

    In ADA you wouldn't be able to do this without duplicating either the
    case-expression (they aren't always simple numbers) or the statements.

In this case, duplicating the statements wouldn't be hard enough to
worry about.  If the bodies of the cases were large enough to make it
hard, you can write a local procedure, and just call it from several
cases.  (Since Ada has nested procedures, you can write a procedure
that has access to local variables.)

    The 11th commandment: "Thou shalt use lint"

In Ada (or any sane language), "Lint" is called "the compiler".
