Lua also has for i, v in ipairs (t) do -- i is the index, v is the value end Not getting the index in C++ easily was very frustrating. Often in C++ I fall back on C-style for-loops just because the functional stuff is hard to remember. In Rust it doesn't give you the index by default, but the `enumerate` adapter adds an index anywhere in a functional pipeline.
