Consider creating a module `A` with a function called `split` inside of it. Then I can call the function as `A.split` without clobbering or extending `Base.split`, so it could have a different meaning. Within `A` I would have to qualify any use of `Base.split`, but otherwise it seems pretty reasonable to me.

```julia
module A
    split(x,y) = "A split"
end
A.split("abc","cdef")

```

The following gives me pause, every module has `Base.split` available at all times

```julia
julia> module B
       end
B

julia> B.split("abc","b")
2-element Array{SubString{String},1}:
 "a"
 "c"

```

Anybody have any thoughts on re-using base function names inside a module? I was trying to avoid something like this, where I essentially repeat the module name:

```julia
module C
    csplit(x,y) = "c split"
end

```
