Comment:
In and of itself, this shouldn't actually be all that difficult, there's
essentially just one hurdle, and one question that needs clarifying. The
latter is simply, would newly declared variables count as such a change or
not? e.g. when stepping into a new lexical block such as an if, where a
declared variable comes into scope for the first time.
The main hurdle is that, currently, Debugger lazily fetches variable
values as the user actually asks to look at them, e.g. a class's member
values aren't actually retrieved until you first click to expand it. As
such, in order to implement this enhancement that behavior would have to
be somewhat changed, so as to have the requisite values to compare between
steps. This then begs the question of what depth to limit that behavior to
though, since part of the reason for the current behavior is to prevent
issues with e.g. doubly linked lists where one can potentially follow
nested member links forever.
