+// Fixed-capacity, statically allocated counterpart of std::vector. Akin to std::array, StaticVector
+// allocates contiguous storage for N elements of type T at compile time, but stores at most (rather
+// than exactly) N elements. Unlike std::array, its default constructor does not require T to have a
+// default constructor, since elements are constructed in-place as the vector grows. Operations that
+// insert an element, such as push_back and emplace, fail when the vector is full. The API otherwise
+// adheres to standard containers, except the unstable_erase operation that does not shift elements,
+// and the replace operation that destructively emplaces.
+//
+// StaticVector<T, 1> is analogous to an iterable std::optional, but StaticVector<T, 0> is an error.
+//
+// Example usage:
+//
+//     ftl::StaticVector<char, 3> vector;
+//     assert(vector.empty());
+//
+//     vector = {'a', 'b'};
+//     assert(vector.size() == 2u);
+//
+//     vector.push_back('c');
+//     assert(vector.full());
+//
+//     assert(!vector.push_back('d'));
+//     assert(vector.size() == 3u);
+//
+//     vector.unstable_erase(vector.begin());
+//     assert(vector == (ftl::StaticVector{'c', 'b'}));
+//
+//     vector.pop_back();
+//     assert(vector.back() == 'c');
