The only problem is the hackiness of having to define something on the
Allegro CL side.  Someone around here put in a more general hack
whereby the load is done from an stream and that stream was built as
an echo-stream.  This means you get to see everything evaluated by
Allegro CL that is sent from Emacs.  I planning a new release of the
interface, but this last neat feature will not work until a patch to
Allegro CL echo streams has been made available (which should be near
the same time of the Emacs/Lisp interface release).
