Yeah, I've had this and the struct redefinition problem since the very early days of Julia, that's why I never fully bought into the Revise.jl based development model (it has its good parts, but these are big limitations that should be mentioned more often when recommending it). That's also why I resisted the removal of the `workspace()`-clearing function (like MATLAB's `clear`), since that would be an alternate option for quick and dirty exploration in a lot of cases; though these days the latency problems of exiting to shell and coming back are much less, so it's not as much of an issue.
