The latter would be a cast from rvalue to lvalue like it happens in 
boost.foreach.
Not sure what you're referring to. Boost.Foreach does no such 
rvalue-to-lvalue cast.
So this wouldn't compile:
vector<int> foo();
...
BOOST_FOREACH( int& r, foo() )
   ++r
?
No, it doesn't compile, and it shouldn't. What would be the point of 
mutating the unnamed temporary vector returned by foo()?
