The obvious advantage to the  myFunc[]:=(whatever) construction is  
that it is possible to expand the function to include argument or  
options at a later time.  With the myFunc:=(whatever) that would not  
be possible since  myFunc[x_]:=(anotherwhatever) would evaluate to   
whatever[]:=(anotherwhatever).
