When should I really use noexcept?
...y, I care about noexcept because of the increased freedom provided to the compiler to safely apply certain kinds of optimizations.
It seems like the biggest optimization gains are from user optimizations, not compiler ones due to the possibility of checking noexcept and overloading on it. Most co...
LINQ-to-SQL vs stored procedures? [closed]
