for me this is the big point. stack-based memory allocation works great as long as your usage and sharing follows the control flow. but when it doesn't, rust really leaves you in a bad spot and you get to play with: - Arcing everything - using a fixed-sized ancillary array and passing indices - creating threads that correspond to the lifetimes you care about - fighting your way through adding explicit lifetime allocations and - delaying reclamation of _everything_ above it on the stack ... and while workable, none of those things are particularly nice
