Base.Cartesian is a slightly-enhanced version of the original Cartesian.jl
package; the README there is (in my personal opinion) quite thorough. The
version in base is intentionally undocumented since we don't plan on exporting
it.
But I'm wondering if perhaps you're simply wondering if you can replace "5" in
my example with something else. The answer is yes:
julia> for N = 1:5
typename = symbol(string("MyType", N))
@eval begin
type $typename
Base.Cartesian.@nexprs $N i->a_i::Int
end
end
end
julia> MyType2.names
(:a_1,:a_2)
julia> MyType4.names
(:a_1,:a_2,:a_3,:a_4)
