I have an array of 2-tuples of floats, created as

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 zipping 
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)?
