Fastest way to determine if an integer's square root is an integer
... doing a bit-wise "and." Perfect squares can only end in 0, 1, 4, or 9 in base 16, So for 75% of your inputs (assuming they are uniformly distributed) you can avoid a call to the square root in exchange for some very fast bit twiddling.

Conveniently Declaring Compile-Time Strings in C++
...) work with this approach? Perhaps using two constexpr-string classes (one based on str_const and the other based on sequence), this may be possible. The user would use str_const to initialize the string, but subsequent operations that create new strings would return sequence objects.

What is the purpose of the “final” keyword in C++11 for functions?
...ady mentioned in a comment is that if you are overriding a function from a base class, then you cannot possibly mark it as non-virtual:
struct base {
virtual void f();
};
struct derived : base {
void f() final; // virtual as it overrides base::f
};
struct mostderived : derived {
