If you want to loop through irregular values use MapThread.

MapThread[
    Print[Switch[#, fall, "Fallen leaves", winter, "Snow flakes", spring,
          "Green buds", summer, "Swim suits"]] &, {{fall, winter, spring,
        summer}}];

Is there a foreach loop statement in Mathematica?  I need to loop through a
list of words, rather than numbers.  I need the equivalent of Do[expr,
{n,0,10,1}], except I need to step through a list like so:  foreach loop
[expr, {fall, winter, spring, summer}].  Can anyone help?
