Right, it was using a modified abcl, but sometime after the 0.3
release I made it work with standard ABCL. Unfortunately, I forgot to
make a new release afterwards.
Now I just released version 0.3.1 that also fixes the problem with
closing the repl, and includes all the post-0.3 stuff that was on
trunk (mainly bug fixes and small improvements, but one API change:
with-widget is now called simply widget). I tested it with the latest
abcl from trunk but it should also work with 0.25 (besides, 0.26 is
not far away I think).

On a side note, today I read news about JavaFX 2.0 entering beta,
being Java only (no ad hoc language) and sponsored as Swing 2.0 (old
Swing is going to die, if it can be even more dead than it is now). I
don't know how things will evolve, but I sense an opportunity for
SnowFX ;)
