When you see some syntaxt that you can't quite make sense of, the O module can really help, for example: 
dos>perl -MO=Deparse -e"splice @cities, (@cities-@states)+1, 0, shift 
+@states for 0 .. @states-1;"
 for 0 .. @states-1;"
foreach $_ (0 .. @states - 1) {
    splice @cities, @cities - @states + 1, 0, shift @states;
}
-e syntax OK

dos>more eff

@cities = (Atlanta, Birmingham, Chicago, Memphis, "New York");

@states = (GA, AL, IL, TN, NY);

print "Cities: @cities" . "\n";

print "States: @states" . "\n";

splice @cities, (@cities-@states)+1, 0, shift @states for 0 .. @states
+-1;

print "@cities" . "\n";

eff syntax OK
