What is Dylan?
http://www.double.co.nz/dylan/ says Dylan is an object-oriented dynamic programming language.
http://www.double.co.nz/dylan/introduction.htm points to 3 implementations of dylan. My first exposure to Dylan was with Apple Dylan, a MacOS project at Apple Computer.
Tk bindings for the Dylan language are being shipped as a part
of CMU's Mindy compiler for Dylan. The Sather language also has a set of classes to bind in Tk/Tcl.
