Midpoints deprecation

General Usage
1

Base.midpoints was deprecated for v0.6, and ostensibly moved to StatsBase, which appears to export the symbol but not define it. So I get Base.midpoints, with warnings. What should I do to get rid of the deprecation warnings?

Is it that midpoints code will be moved to StatsBase from Base for v0.7, and this was a shortcut as a prelude to that?

julia> using StatsBase: midpoints

julia> midpoints(1:2:10)

I have not problem in 0.6.1

julia> midpoints(1:2:10)

julia> using StatsBase: midpoints

julia> midpoints(1:2:10)
2.0:2.0:8.0

v"0.6.1"

But 0.7.0 is problematic:

julia> using StatsBase
[ Warning: Replacing module `Compat`                                                                                                                   @ Base loading.jl:350

julia> :midpoints in names(StatsBase)

I think that deprecations only show up once, so by calling it in Base you don’t get it after.

You are right!

Now it seems interesting to me that StatsBase.midpoints is “replaced” with Base.midpoints:

julia> import  StatsBase

julia> @which StatsBase.midpoints(1:2:10)
midpoints(r::Range) in Base at deprecated.jl:56
