@item (compiler-macro @var{expander})
This can only be used for functions, and tells the compiler to use
@var{expander} as an optimization function. When encountering a call to the
function, of the form @code{(@var{function} @var{args}@dots)}, the macro
expander will call @var{expander} with that form as well as with
@var{args}@dots, and @var{expander} can either return a new expression to use
instead of the function call, or it can return just the form unchanged,
to indicate that the function call should be left alone. @var{expander} can
be a symbol, or it can be a form @code{(lambda (@var{arg}) @var{body})} in
