My understanding is that when you type `x=1` in the REPL, it adds an `x` binding in the Main module, it’s a bit like typing:

```julia
module Main
    x = 1
end

```

It seems Julia keeps some sort of list of [all the bindings](https://github.com/JuliaLang/julia/blob/6a02edfae865054cdc643580ba5fc5269c1654a9/src/module.c#L661) in a module, is there a reason why we can’t remove an element from that table ? e.g. `delete!(Main,:x)`.

Otherwise maybe something like [REPLinModule](https://github.com/tshort/REPLinModule.jl) might a workaround, to get a clean workspace you would do `module Testing end`, `REPLinModule.set(Testing)` and your REPL would then be evaluating in an empty module (which is more or less what workspace does, as I understand).
