In that case, it _should_ have been:

    set vertex_set of vertex
    for a_vertex = set$element in vertex_set

Assuming that the two statements above may be separated in the program
by many lines (even pages) of other code, the "vertex_set" variable is
_MUCH_ easier to read, maintain, and even to _WRITE_!
