I have an array of 2-tuples of floats, created as
```julia
julia> mytuples = (Float64,Float64)[(v.x, v.y for v in vs] # slightly more
complicated in actual code
136-element Array{(Float64,Float64),1}:
(4.0926,-2.55505)
(4.170826,-2.586752)
...
```
Now, I'd like to split this into two arrays of floats. I was under the
impression that `zip` could do this for me - according to the docs, [`zip`
is its own
inverse](http://docs.julialang.org/en/latest/stdlib/base/#Base.zip), and
the array of tuples does look like something I could get from `zip`ping two
arrays. So I tried something similar to the example there:
```
julia> julia> [zip(mytuples...)...]
2-element Array{(Float64,Float64,Float64, ... and so on, 136 times...),1}:
```
so I guess that only works on actual `Zip` objects, and not on arrays (that
could have been) generated by the `zip` function inside `[]`. (Also, since
this uses splatting with `...` on large lists, it [might not be a good idea
in the first
place...?](https://github.com/JuliaLang/julia/issues/6098#issuecomment-37203821))
What's the best way to accomplish what I want, i.e. transforming the
`mytuple` variable above into two `Vector{Float64}`s (possibly inside a
tuple or array or something)?
