Jared,
You might be interested in what I consider the most useful Julia function
that's not actually in
Base:
http://stackoverflow.com/questions/29661315/vectorized-in-function-in-julia
vectorin(2, s)
0-dimensional Array{Bool,0}:
true
vectorin(s, 2)
3-element Array{Bool,1}:
true
false
false
although perhaps I'm misunderstanding what you want to do here. -A
