A great fan of Tcl/Tk back in the late 1990s, recent (2011) advances in CoffeeScript + HTML 5 Canvas are strongly reminding me of Tcl/Tk's value proposition.
Javascript, although thriving, is waning as a programmer language. Other languages compile down to Javascript.

incr Tcl in Javascript would have promise for giving Tcl relevance if finished and fortified with industrial strength.
