Most of the modify macros defined by Common Lisp do not exactly
follow the pattern of @code{define-modify-macro}. For example,
@code{push} takes its arguments in the wrong order, and @code{pop}
-is completely irregular. You can define these macros ``by hand''
-using @code{get-setf-method}, or consult the source
-to see how to use the internal @code{setf} building blocks.

@defun get-setf-method place &optional env
This function returns the setf-method for @var{place}, by
invoking the definition previously recorded by @code{defsetf}
values as described above. You can use this function to build
your own @code{cl-incf}-like modify macros.
@c These no longer exist.

The argument @var{env} specifies the ``environment'' to be
passed on to @code{macroexpand} if @code{get-setf-method} should
@code{substring}, which works by calling @code{get-setf-method} on a
simpler case, then massaging the result.
