Thanks.  I'd seen that mentioned above, but I'm a bit new to Haskell and didn't 
really understand what that meant.  In fact, I still don't.  Do you have any 
good resources on that?  None of the tutorials/manuals were entirely clear to 
me, nor was the wiki(http://www.haskell.org/haskellwiki/Constructor), which uses 
the same statement as the example of both type and data constructors.
