I'm glad you enjoy them, writing and using these languages floats my boat but it's always nice to get confirmation that I'm not alone in here :) The biggest issue with g-fu is that it currently expands macros on evaluation. What can I say, it was the first time I implemented quasi-quoting which twisted my brain in exotic ways. That's also why it's so close to Lisp, because it's the only decent macro system I have experience from. g-foo is definitely a cleaner design, but more Forth than Lisp which may not be everyone's cup. Agreed, and Bjarne said so himself; that there's a cleaner, more consistent language hidden deep inside C++. C compatibility has been a blessing and a curse. I think Stepanov is a better designer though; if it wasn't for the STL, I would have given up a long time ago.
