No, that's not how structured bindings are specified to work. There are not
variables 'a' and 'b' defined. Instead a variable 'e' is created from the
initializer expression, and then the identifiers 'a' and 'b' refer to members
of 'e'. The type of 'e' in your example is 'foobar'.
http://en.cppreference.com/w/cpp/language/structured_binding is a good
explanation.
