"- The instantiation of `StaticArray< float, 5 >` is implicit. Thus, it is lazy. The compiler knows that the member function `getSize()` exists and what its prototype is, but it will not generate machine code for it, as it is never called.\n",
"- The class `StaticArray< float, 5 >` itself represents a datatype. While we can have multiple objects of this type, the template will only be instantiated once, for the same arguments.</br>\n",
