While there is no high-level way to add user extensions to @code{cl-loop}
(comparable to @code{defsetf} for @code{setf}, say), this package
does offer two properties called @code{cl-loop-handler} and
@code{cl-loop-for-handler} which are functions to be called when
a given symbol is encountered as a top-level loop clause or
@code{for} clause, respectively. Consult the source code in
file @file{cl-macs.el} for details.
