Decision on export of Base modules names

[kmsquire]

As pointed out by @nolta here, the exports in Sort are imported into Base with importall, and the majority of those are reexported by Base.

There are some unexported functions, but use of them should be rare, so it seems reasonable not to export Sort itself from Base, and anyone who needs Sort can import Base.Sort.

1. Do people agree that this is reasonable?
2. If so, there are a host of other modules (below) in the same situation. Which of these, if any, should be exported from Base?

Obvious modules meant to be used with the module name include Pkg, Pkg2, and Profile; these should still be exported. Others?

readlines(open("sysimg.jl"),strip) |> 
           x->filter(y->beginswith(y, "importall"),x) |> 
           x->[split(y)[2][2:end] for y in x] |>
           x->filter(y->isdefined(symbol(y)),x)
11-element Any Array:
 "Math"        
 "Random"      
 "Order"       
 "Sort"        
 "SparseMatrix"
 "LinAlg"      
 "DSP"         
 "GMP"         
 "MPFR"        
 "QuadGK"      
 "Profile"

Beat me too it ;)

Yes, i say we stop exporting these modules, if possible.

The common usage of the sorting and ordering APIs don't require access to these modules anymore, so yes, we should stop exporting these. I mostly didn't change things because I wasn't sure about a smooth deprecation strategy but maybe we should just not export them and let people fix their code when it breaks.
