Seriously ... these points in favor of the image are so m00t. Lets see how it would work without an image:
I write a C application which I link to GCC. Now I run GDB on my application, and while running I have the whole GCC compiler collection at my disposal while running. While debugging (at some breakpoint) I just let the GCC library compile some C code for me; I turn on the executable flag and whooptidoo, I have a Smalltalk like debugger for C.
This is totally unrelated to having an image; it's just a great debugger implementation. 2 completely different things. No reason why this wouldn't work for C; except for the fact that they didn't do it yet (those lazy bastards).
ok, true :) but, it's not only the debugger... getting senders, implementers, class that use it, methods that contains this word, ... of course, this is doable with files (see eclipse *sigh*), but I prefer the snappy feeling of an image for that...
