Variable tracing works fine, with Tcl_SetVar(). I've added a demo to
Tash at r162, see also at Dropbox[1].
Note, this demo is syntactically correct, but I'm concerned that it's
synchronous, whereas the only sensible use case is asynchronous (the Ada
model generates a new value in response to an input of which Tcl is
unaware). More thought needed.
