There are some members of mathgroup who seem to believe that when
solving  equations using Solve, Mathematica assumes that the variables
are real or  complex numbers, or that it uses limits (in other words,
assumes a  topology) or that -> means "gets closer and closer to". I
suggest these persons consider the example I have constructed just for 
them:

In[1]:=Solve[(x-"dog")*(x-"cat"),x]
Out[1]:={{x->cat},{x->dog}}

Please note that "dog" and "cat" are strings, not symbols!
