C++ Enumerator

Small header-only C++ function to mimic Python-style enumerate() ranges in for loops.
Used to automatically get index and value when enumerating lists with for loop.
Function works simillar to Python's enumerate() or Rust's .iter().enumerate()

Example

#include "enumerator.hpp"

std::vector<std::string> v = {"a", "b", "c"};
for (const auto& [i, value] : enumerator::enumerate(v)) {
    std::cout << "String " << value << " has index " << i << std::endl;
}

Output

String a has index 0
String b has index 1
String c has index 2
