The fact that you have to use "likely" means it's just a guess and no longer a sharp "line in the sand" as I originally described. Languages that operate on large data structures (like Julia and R) may have a similar design to using higher-order/callback functions like qsort everywhere, but those hotspots will always be in the language/standard library even when programs are compiled. I just don't think it's a reliable enough metric for this distinction.
