All the GUI is done in .NET and embedded into ECL (and not the other
way around). However, there's also a LISP part to define the
communications
channels between the LISP REPL (which runs in a separate thread) and the
shell window, based on gray streams, and to implement all the LISP-aware
operations like symbol/pathname autocompletion, bytecoded functions
calltip.
I expect the LISP part to grow significantly while adding LISP specific
features.

For the time being, debugging is quite limited. I re-implemented a REPL
loop, largely based on the top.lsp code (here I notice a "problem" when
you want to overload things in compiled code, see below). The current
debugger only allows you to quit it, but I expect to add more useful
features like meaningful backtraces...
Nevertheless, I would say that it could do whatever you want as long as
you implement it :-) Using RDNZL, you have a complete control on the GUI
from LISP. If ECL can produce nice debugging information, putting it
into
a window is easy. This explains my previous mails about function/macro
declaration info and argument/value mapping.
