One way to handle that (changing the patch a bit) is to require all user 
defined operators to be of the form \|.*\| e.g., |+|, or |-|.  That 
would allow all user defined operators to be easily distinguished from 
the built-ins.  This would allow any desired builtins to be added later, 
and also make the user defined operators readily recognizable.
