Ha, yeah, you've captured it nicely. I have a TODO list 25 items long of problems to try to track down; occasionally I'll pick one off, but I think the list is growing faster than it's shrinking.

It's an open question, but I suspect it's not impossible to have both a robust and flexible system...think Emacs, but instead of the wild-west of Lisp as the extension language, something more in the vein of Rust...
