I was going to worry about that if I could get a java example to work.
Since I can't do the latter, I won't bother with the former. I borrowed
these imports from tinybasic.java:

> import antlr.debug.misc.*;

The new code compiles Ok with with javac, but the interpreter always
comes up with the same error whatever I do ("Exception in thread "main"
java.lang.NoClassDefFoundError: antlr/collections/AST").

Who on earth actually uses Java anyway? ANTLR has one of the steepest
learning curves of any tool or language I've ever used; learning Flex
and Bison is trivial by comparison. Forcing users to be Java-literate as
well really doesn't help.
