No. I've looked at it a couple of times, but haven't been able
to work up the enthusiasm (or time) to really learn it.
My (admittedly cursory, and lightly-held) opinion on its "dialecting"
capability arises from these two observations:
1) The syntax of Tcl commands revolves around a simple
verb param-a param-b param-c...
statement format.
2) There's apparently a well-documented and widely-used set of
conventions for writing extensions that present externally-
written c functions/libraries as Tcl commands (and, BTW, for
embedding Tcl as a command interpreter into c programs).
Those led me to the view that it would be easy to write code (either
in Tcl or as an extension) that would have the appearance of adding
new verbs/commands to the language in a manner that would be
indistinguishable from "built-in" features. That's the sense in
which I was referring to "dialecting".
Of course, that's not unique to Tcl, but it also doesn't quite fit
the REBOL concept of a dialect either...
