Is it possible to get a list of global variables used in a function
from the compiler? Currently, I am using clisp with maxima, and
xref is being used to do a crossreference. However it lists
local variables and global without indicating which ones are global,
and that information would be a big help.

if the function is a compiled closure, then yes: look at the
GETVALUE and SETVALUE instructions in the byte code.
if it is an interpreted closure, the code-walker would need to be
modified to do this..
if it is a built-in function written in C, no.
it would be nice to display this information in the disassembly...
you probably want a CLOSURE-FREE-VARIABLES function, right?

Booze is the answer. I can't remember the question.
