The mechanism by which one customizes a system so that Lisp files
may use a different extension from the default @file{.lisp} has changed.
Previously, the pathname for a component was lazily computed when operating on a system,
and you would
@code{(defmethod source-file-type ((component cl-source-file) (system (eql (find-system 'foo))))
(declare (ignorable component system)) "cl")}.
Now, the pathname for a component is eagerly computed when defining the system,
and instead you will @code{(defclass my-cl-source-file (cl-source-file) ((type :iniform "cl")))}
and use @code{:default-component-class my-cl-source-file} as argument to @code{defsystem},
as detailed in a @pxref{FAQ,How do I create a system definition where all the source files have a .cl extension?} below.

@subsection How do I create a system definition where all the source files have a .cl extension?
First, create a new @code{cl-source-file} subclass that provides an
initform for the @code{type} slot:
(defclass my-cl-source-file (cl-source-file)
((type :initform "cl")))
@end lisp
Then make your system use this subclass in preference to the standard
