CLISP and Unicode

[unicode logo] CLISP fully supports Unicode 3.2: here is a Lisp file with Japanese characters in it, run in xterm:

(also edited in GNU Emacs).

CLISP and CLX

Here is a demo of the CLISP new-clx module (with the xshape extension):

CLISP Performance

CLISP compares well with other ANSI CL implementations with respect to performance in most areas, such as CLOS, I/O, lists, integer arithmetics (CLISP's bignum performance is better than that of most other CL implementations). The worst performance CLISP exhibits is in the area of floating point arithmetics. While showing nothing spectacularly bad and easily outperforming Java, Perl, TCL and any Scheme interpreter, CLISP is slower than another open-source CL implementation, CMU CL, which outperforms C and FORTRAN. If your code is heavily numeric, you might prefer CMUCL, otherwise CLISP is a wise choice.
