Yes, you're right, Tcl suffers from lack of Scheme-like macros. While a lot can be done using procedures, methods and introspection "tricks", often enough it's far from elegant. However I haven't been stymied all that often. Missing functionality can sometimes be provided by C-API extensions which I've gotten pretty good at writing. Completely agree about the utility of Tk. I remember reading somewhere that HTML/CSS widgets were influenced by Tk. Don't know how true that is but I can see how it could be.
