In regards to the properties of &REST arguments: There may be a way to
have our cake and eat it too given that CL has a declaration mechanism
in place already and optimization hints are considered first class citizens.
I propose an anology to the SYS:DOWNWARD-FUNCTION and SYS:DOWNWARD-FUNARG
decls in the Symbolics implementations. In the function with the &REST arg,
that arg could be declared DOWNWARD meaning that pointers to it and top-level
Lucid uses the declaration DYNAMIC-EXTENT for this purpose.
