In Common Lisp, symbol macros are generally not defined at the toplevel through DEFINE-SYMBOL-MACRO, as the usefulness of symbol macros defined this way is limited and prone to confusion. So when a Common Lisp programmer needs to define a symbol macro, it usually works to use SYMBOL-MACROLET instead.
