In CommonLisp, is there a way of checking, at run-time, whether a particular
expression is valid as a type specifier? Can't seem to find anything in
the manual that does the trick. One possible method might be to call
(typep t type-expression), and use the error handler to recover if this is
an error, but this approach isn't very elegant, and probably not too efficient
either.
Thanks,
David
