If performance matters, currently you're going to have to specify the element
type---not for the sake of your `MyType` object, but simply for the efficient
access to elements of c and d. This will change once
https://github.com/JuliaLang/julia/pull/15921 merges. On julia 0.4, you could
write
Say I have something like
type MyType{T}
a::T
b::Vector{T}
c::Vector{Vector{T}}
d::Vector{Matrix{T}}
end
MyType(3, [3, 3], Vector{Int64}[[3,3], [4,4]], Matrix{Int64}[[3 1],[1 3]])
MyType(3, [3, 3], Vector[[3,3], [4,4]], Matrix[[3 1],[1 3]])
The first call to the MyType
