Repeated class qualifier is accepted. Why?

A colleague sent me code similar to the following:

#include <iostream>

class Weird
{
public:
    Weird();
};

Weird::Weird::Weird::Weird::Weird::Weird::Weird::Weird::Weird::Weird::Weird::Weird::Weird::Weird::Weird::Weird::Weird::Weird::Weird::Weird::Weird::Weird()
{
    std::cout << "Ok, this is weird.\n";
}

int main()
{
    Weird a;
}

It compiles and runs and produces "Ok, this is weird." I tried it with g++, clang, and msvc with online compilers and it works on all of them.

Why is the repeated class name qualifier accepted? Is this intended by the standard?

This is a dupe, I'll have a target in a minute – NathanOliver Nov 21 '19 at 17:53
@NathanOliver-ReinstateMonica: Thanks. I tried to find one and didn't, so I asked. Some questions are just darn hard to search. – Fred Larson Nov 21 '19 at 17:54
No worries. Unless you know the term, it's hard to find – NathanOliver Nov 21 '19 at 17:54
I'll leave this up. Maybe it'll make it easier for someone else to find. – Fred Larson Nov 21 '19 at 17:55

@FredLarson Which is exactly what you're supposed to do with duplicates. Duplicates are good for the stack, they help with SEO. – Xirema Nov 21 '19 at 18:06
