In the past you have shown to want very stable, out of the box usable, "I can not do anything wrong" kind of software. Does it then make sense to use Nautilus, which is in active development?

I've thought of something very similar, and never got around to doing anything with it, namely to do what you suggest above, only also display the "sub" methods - methods of the subclasses. I'd like some options, too: I'd prefer to see these things expanded by default, for instance, while you'd prefer to see them collapsed by default. > 2.

Which means you'd want to memoise everything within this context? There's a difficult tradeoff to be made here, I think: as you say, invoking a method may cause side effects (even if YOU write purely functional, side-effect-free code, the code you call may not!). Which means sometimes you want to see how you got to where you are - memoising the method calls so the debugger remembers the precise history of the calculation - and sometimes (after you press <restart>) you want to replay the computation, side effects and all. How do you think you could present these options in the debugger? As simply as "memoise until <restart>, and then clear the cache" as a default behaviour? > Â This might > take the form of hovering or right-clicking on any message an choosing > something like 'inspect context'.
