I finally got through the second talk. It was really... disappointing. It
felt like cheap circus for little kids. We all know that some logic
deductions can be made in a trivial cases. I did not see any adult
discussion about why they believe these examples are representative. IMO
99.999% of the real use case will not like this branch-less, loop-less
code. Real code will look more like:

void foo( int i )
   vector<int> v{1};
   int& ref = v[0];

   if( i%2 )
     v.push_back( 2 );

   if( i%2 )
     i = ref;

What is their local static analysis suggest us to do in this case? If code
is wrong, how should we write it in modern C++?

I do not want to discourage this effort by no means, and I really believe
we can use modern C++ to produce much better code. Yet, this talk did not
lift my spirit.
