I'm going to have to disagree with you there. I learned programming in
1987 and I didn't have any such features.

Such a feature requires pretty tight integration with the VM, or at
least the debugger. It requires being able to preserve the exact state
of the running program and FIND the equivalent place in the new
version of the program to resume. Certainly this isn't an impossible
task, as ZeroBrane does it just fine, but this isn't something you can
just tack on and it's certainly not a feature of the language -- it's
a feature of the development environment.

If your development methodology is tied into having this feature,
you've got a lot of learning to do.
