with the u++ moving to c++17,

code like this (Core/Vcont.h line 13)

	void Malloc(size_t size) {
		if(std::is_trivially_destructible<T>::value)
			ptr = (T *)MemoryAlloc(size * sizeof(T));
		else {
			void *p = MemoryAlloc(size * sizeof(T) + 16);
			*(size_t *)p = size;
			ptr = (T *)((byte *)p + 16);
		}
	}

can benefit from constexpr-if compile time trimming to produce more compact and faster binary (theoretically).
