Excellent comment; even better. :-) And since we're not interrupting the
I/O stream with the exception, we can probably get rid of the byte.
An alternative would be to add an Observer (actually, wouldn't that be a
Listener, to remain consistent with Java terminology? :-)) with the pattern,
although it seems that none of the regex engines support compiling multiple
patterns, which I find truely bizzare. That would allow the Listener code
to execute as each pattern is found in the stream.
I would expect further interface tweaking, but the first thing we need is
code capable of supporting this construct.
