This solution is based on improvements done on a pull request that was probably already changing too many things to the great original repository: icemanbsi#11
I would be happy to merge pull request proposals provided that:
- they don't break the compilation
- they pass the automated testing
- they provide the relevant adaptations to documentation and automated testing
- they bring value
- they don't completely transform the code
- they are readable (though, I enjoy https://www.ioccc.org/ as a contest full of curiosities)
Contributions and forks are very welcome!
