No, vec doesn't help because I have an array of arrays (actually a vector of vectors), not a multidimensional array. (I think vec would actually be a noop...)
Flatten.jl might provide some useful idioms, but my application is json deserializing, so I can't restrict myself to fixed-size containers. I have to investigate my particular needs, though - it's possible that I don't need infinite-depth recursion at all, in which case it might be better to just do something hard-coded that solves the immediate problem. Thanks anyway! // T
