While investigating, I notice that there seems to be consensus that fixed size arrays can offer a real speed boost (https://github.com/JuliaLang/julia/issues/5857). ImmutableArrays offer something like this already, but I feel that pathtracing is a little too dynamic to make effective use of them. Mike
