A perfect application of revoking the audible capability to the poor
little non-squeaklet. Feed the annoyance some bytecodes and perhaps
he'll pipe down. Java, JMS, J2EE, JTS, XML, XTS, XSL, SOAP, RMI, CLR,
ML, Ocaml... whatever. If there's no market for secure Smalltalk,
so we just have to create our own.
yeah, Lex. Let it be known.

Which nincompoop was that? Squeakers are the smartest group of people
I have ever had the pleasure of working with. Come join the new list
and let's see what ferments, or rather foments.
Thanks for your fantastic posts these past few days. I have really
enjoyed reading them.
ps. Let's transition the discussion to squeak-e. We should leave the
other 900 squeakers alone, at this point ;-)
