> That has nothing to do with the tooling, though. C++ just doesn't support those features. In principle I don't see how language definition not supporting this would make this entirely impossible. It's just not possible to ask for such a running program transition to be requested from within the language, but with some modest restrictions on program behavior this might be possible to request from within the IDE. The restrictions I imagine to be similar to the restrictions that would enable C++ code to be subject to code-agnostic tracing GC, such as no user-defined XOR-linked lists.
