(no automagic memory management, no garbage collection, no functional programming). That's a big drawback. Common Lisp (SBCL) is very fast already, and one can avoid the GC overhead in a number of interesting situations (though not all). Are there benchmarks comparing SBCL and Lush? Has anyone found a sane way of doing maths (linear algebra, etc.) in Common Lisp? My experience with the GNU scientific library has been disastrous.
