use of [] in base

[my-little-repository]

There are a few uses of the [] array (aka None[]) in base. It was suggested in another issue https://github.com/JuliaLang/julia/issues/8092 to provide an element type for the array whenever possible. Here are the occurrences of [] for julia Version 0.3.1-pre+4 (2014-08-22 11:13 UTC) obtained from emacs with the command M-x rgrep RET " \[\]" RET *.jl RET ~/path/to/source/directory RET:

I don't think any of these uses are problematic. Empty None arrays aren't bad, they're just kind of limited.
