Consider using range library

[scarf005]

codebase need better way to manage ranges, something like...

for ( int i : range( v.size( ) ) ) { 
  for ( int j : range( -3, 3 + 1 ) ) { 
    // ...
  }
} 

for ( auto&& [ i, value ] : enumerate( v ) ) {
  //  ...
}

possible candidates

implement a own.

or:

https://github.com/klmr/cpp11-range

pros: small, single header, performant
cons: only has ranges

https://github.com/ryanhaining/cppitertools

pros: python-like syntax, tons of itertools to clean up code
cons: heavy (lots of headers), official build tool only supports bevy and scons

C++20 ranges

pros: C++ standard.
cons: need to migrate to C++20, #1624 is WIP

https://github.com/ericniebler/range-v3

pros: superset of C++20 ranges library
cons: long compile time

I'd say C++20 or our own. I'd rather not add more libraries for now.
