[julia-users] Get a vector of field values from a composite type array

[Chris]

Sorry for the awkward wording. Here's an example:

julia> type MyType
       x::Float64
       end

julia> v = [MyType(float(i)) for i in 1:50];

My question is: how do I best recover the values of x for all elements in v. 
Here's the way I do it now:

julia> u = [v[i].x for i in 1:50]

This has the unfortunate effect of giving me an Array{Any,1}, but I can 
apparently fix that with map(Float64,u), according to the deprecation 
warning. Is there (a) a more convenient way to do this, and (b) a more 
efficient way?

Thanks,
Chris
