Re: rule based program for "Deleting repeated members of a list."

this is really odd....


In[1]:=s = {a, b, c, c, d, e, e, f, g, g, g, h, a, b} // Intersection

Out[1]=
{a,b,c,d,e,f,g,h}

In[2]:=s = {a, b, c, c, d, e, e, f, g, g, g, h, a, b} // Union

Out[2]=
{a,b,c,d,e,f,g,h}

In[3]:=s = {a, b, c, c, d, e, e, f, g, g, g, h, a, b} // Complement

Out[3]=
{a,b,c,d,e,f,g,h}

I'm guessing it's use of these functions on single list of values that
makes them behave like that...
