Does redefining functions with dependencies in the REPL work with this release? How about deleting items from the symbol table?
Not sure about the second part, but `workspace()` was added in 0.3 (https://github.com/JuliaLang/julia/blob/release-0.3/NEWS.md, https://github.com/JuliaLang/julia/issues/1195)
Looks like workspace() wipes the whole slate clean. I was thinking along the lines of R's rm() that can target individual variables.
