   I would call this a bug. Since f[x_] and f[y_] represent exactly the 

   same patterns, I don't see any reason for Mma to keep both 

   definitions ... ?

   Anyone's got some viewpoints on this?

Although I have many problems with Mma, this is one of the more minor ones.  
Essentially, you're asking for automatic garbage collection -- which should  
be pretty easy.

This problem can be handled relatively easily by doing a Remove[f2] to reset  
the definitions. I learned the hard way that I needed to incorporate an  
initial Remove[] of all variables and functions whenever I was developing a  
package. Such a habit helps to reduce the hate and discontent which Mma can  
generate. It allows you to change the function definitions with some
