Result = 8
The ⟳ ¦ ⟲ represents the "symbolic form" of an Eiffel across loop. In the case above, we use two ⟳ (loops) to set the `l_distance' array elements, and then two nested ⟳ (loops) to walk the distance computation.
Also—the `ic' is this programmers shorthand for ITERATION_CURSOR. Therefore, in the nested loops, the `ic' is the iteration cursor following `i' and the `ij' is following `j' as indexes on the source, target, and l_distance.
