compatibility package for ANSI CL?

Dear Symbolics users,

is there a package that integrates all the stuff that would allow compliant
ANSI CL programs to run unmodified on Genera 8.3?

While trying to run code, I've found that things like READ-SEQUENCE,
DECLAIM, (LAMBDA ...) without #', and more, are lacking.
These are small things, but I feel like the Right Thing would be to
patch genera toward learning CL rather than backporting to Genera
(or maybe you will convince me that it isn't).

Are there already patches available somewhere?
If I have to make my own, where should I begin from?
(I'm currently perusing S C patch in DocEx...)
What is the Right Thing to do, and what are the catches to avoid?
Is it the right thing to modify the FUTURE-COMMON-LISP package,
or should I make a new package that imports symbols from it, and
exports new ones? Is it the right thing to modify files and patch them,
or to add new files? I'm told there is already a READ-SEQUENCE somewhere;
where is it, and how should I have found it? etc.

Trying to get the Lisp lore without a guru at hand is not easy.
Did you bootstrap your learning by being in contact with gurus,
or did you have tips to learn without a guru at hand?

Yours freely,
