> I assume that means "efficient at runtime" - but by what metrics? CPU time? Memory usage? Power usage? Latency/responsiveness? Throughput? Not OP, but coming from Python, I find it is liberating to say: I need to write a for-loop for things, and it is OK, not going to be the most efficient thing, but it won't slow me down 1000x and become the major bottleneck. That has been said, Julia probably do the same thing.
