I had a similar desire. The `@with` construct is fine for coding but not very convenient for interactive work. My thought was not to have a mutable value but rather to enter and leave scope with separate commands, something like

```julia-auto
julia> @newscope x => 2.5

julia> # some interactive coding

julia> @endscope

```

Based on the answers to my question [How do ScopedValues actually work?](https://discourse.julialang.org/t/how-do-scopedvalues-actually-work/133270) I gather that scope changes are implemented in core Julia and thus something like this cannot be implemented in a package. But perhaps it is doable in principle?
