[TCLUG-DEVEL] Inner, anonymous classes?

[Liz Burke-Scovill]

hrm - but my reply didn't answer your question did it - I don't think this
is an anonymous inner class, or if it was supposed to be, was not done
properly - in that it calls a constructor for  a named class, and don't
provide any anonymous class definition...
