(Disclaimer - I don't use MSVC, don't use edit-and-continue, and don't
do C or C++ coding on Windows.  That may make me ignorant.)

Let's give the developers the benefit of the doubt here - sometimes
features are not implemented because doing so would be impossible, or at
least ridiculously hard.  And sometimes it is because there are few
people who want the feature or care about it - it might seem a
marvellous idea to one person but it is not going to be implemented
unless there are many people who would find it useful.  And occasionally
it is because they think the feature is a misfeature, directly
counter-productive, or will limit other features or future efforts.


As far as I understand the way Windows works (and I could be wrong
here), this is likely to be /very/ difficult to implement.  I don't see
it as being a very important feature - if you are debugging a running
program and make changes to its code, leaving your debugger attached
seems reasonable.  (Perhaps MSVS only lets you use one debugger at a
time, in which case it would be more of a hardship.)  And it is easy to
see a world of abuse possibilities if there were tools to let you attach
to a running program, change the code, and disappear without a trace.
