• Perl: can I skip the intermediate hash variable in this case?
• Random numbers in C++11: is there a simple way to seed the generator in one place of the code, then use it in different functions?
• Template argument deduction for class templates in C++17: am I doing it wrong?
• Perl: tr/// is not doing what I expect whereas s/// is
• The value of a const variable is or is not usable in a constant expression, depending on the variable type
