Actually, I’ve come to suspect that if you’re sufficiently devious it may not quite be true. I haven’t tested so I can’t promise this will work, but here’s a sketch of how I’ve imagined implementing breakpoints. For a “method” with 2 interior breakpoints, Rebugger would put code on your command-line that looks something like this (if you’ve not looked, [the docs](https://timholy.github.io/Rebugger.jl/latest/internals.html) might help explain some of this):

```julia
rebug> @eval SomeModule let (vars..., label_at_exit) = getstored(uuid) begin
          @goto $(label_at_exit)
          # somecode
          setstored!(uuid, varnames, varvals, :label1)
          throw(StopException())
          @label label1
          # code just after the first breakpoint
          setstored!(uuid, varnames, varvals, :label2)
          throw(StopException())
          @label label2
          # code just after the second breakpoint
      end

```

So if you enter this at the top, it will store program state just above `label1` and then exit. (The `StopException` would be caught by Rebugger…or maybe that should just be a `return nothing`? Not sure.) Because it stored the label at which it exited, and loads from that storage at the top, if you just re-run this same command it will begin at `label1` and continue on to `label2`.

I’m sure this will need some modification, but this is the general gist.
