mid(X) doesn't work for a IntervalBox in 0.7

[eeshan9815]

Both mid(X) and mid.(X) seem to hang on Julia 0.7
mid.(X.v) works absolutely fine though.

Oh :/
Thanks for the report. Probably something to do with the broadcasting?

[eeshan9815]

Possibly due to JuliaLang/julia#26435

#176 makes broadcasting work, but it's currently very slow, so is presumably not the correct solution on 0.7:

julia> using IntervalArithmetic, BenchmarkTools

julia> X = IntervalBox(1..2, 3..4)
[1, 2] × [3, 4]

julia> @btime mid.($X.v)
  5.186 ns (0 allocations: 0 bytes)
2-element StaticArrays.SArray{Tuple{2},Float64,1,2}:
 1.5
 3.5

julia> @btime mid.($X)
  159.861 ns (5 allocations: 208 bytes)
2-element StaticArrays.SArray{Tuple{2},Float64,1,2}:
 1.5
 3.5

julia> @btime mid($X)
  147.446 ns (4 allocations: 160 bytes)
2-element StaticArrays.SArray{Tuple{2},Float64,1,2}:
 1.5
 3.5

This is now fixed.
