I thought one of Julia's compelling features is the ability drop down to the level of index arithmetics without losing performance (as Python does, once you start writing manual for loops).

If I want to stick with higher-level construct for dealing with "collections of numbers", I can use numpy arrays in Python, the STL in C++, etc.

Do you think Julia's high-level constructs are much better than the competition? E.g., how do they compare with C++20 ranges?
