[Cs3] no, you cannot reassign (rebind) a reference, or can you?

[Mikhail Nesterenko]

CS3 students,

This is from today's lecture on references. Officially you are not
allowed to reassign a reference. After

	int &b = a;

reference "b" will always be assigned or bound to "a". However, C++26,
the brand new standard, suggests an alternative: So called optional
references. Here is a link for the curious:
