It (clc) depends on load-time-value, physical and logical
pathnames in order to work properly.  The script was inspired
by similar scripts for CLisp and SBCL.

If you read through the script you'll notice a work around
for load-time-value that I have no idea if will work, but once
pathnames (physical and logical) are more or less up to date
(Thank you for taking a stab at this Michael!) -- yes -- clc
should just work out of the box with that script.

The load-time-value work around which I don't trust:

                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Just like identity, but without the load-time semantics...
Bad and not very predictable, but let us see what happens.
