The closest thing that avoids the overhead of creating an array first would
currently be a loop:
s = Set(Int)
for i in 1:5
push!(s, i*2)
end
At some point, if (when?)
https://github.com/JuliaLang/julia/issues/4470
gets added, it will be easy to add support for syntax like Set(Int, i*2 for
i in 1:5), where the second argument implicitly creates an iterable type.
