There are a few bugs, but most of this should be useful. Please do note, however, that most of the apparent bugs are in fact results of buggy versions of Java. In particular Netscape 2.0 and 3.0, Natural Intelligence's Roaster, Java Workshop, Symantec Cafe, Sun's JDK for the Mac, and most other Java implementations have trouble with at least some of these examples. Before reporting a bug I'd appreciate it greatly if you can test it first with Sun's Solaris JDK. If that's not possible, Sun's Windows95/NT JDK is almost as good.
