    Re:   macro expansion

    ... The only quibble I have is whether we want to spell *MACROEXPAND-HOOK*
    with the stars.  We should only do this if we decide to spell all (or
    almost all) built-in global hooks this way...
-----
As I mentioned at the last common lisp meeting, I advocate the *...* naming
convention for two reasons:

 * It clearly identifies special variables. Makes it easy to tell which
   compiler "... undeclared, assumed special" warnings are worth worrying
   about.

 * It means that variables and functions are in different namespaces, which
   may be important in the package system you devise since currently there is
   no way to export only the value cell or only the function cell of a symbol.
