C&P error. Should have read

Now, with P0608 in place, we have conflicting behaviour, but the variant case is "sane".
int func( string )
{
   return 42;
}

int func( bool )
{
   return 19;
}

int x = func( "Hello" ); // x is 42
int y= func( "Hello"s ); // x is 42

std::variant< bool, string > z;
z = "Hello World"; // z holds a string
