Detailed Description

template<class Component, std::size_t Dim>
class MyVector< Component, Dim >

This test tests for a regression, where std::is_assignable would return true for certain assignments, but it was not actually possible to instantiate those assignments. In the fix std::is_assignable was fixed to report false, and that is what is checked now.
