Comment (by anonymous):

 Yes, this really is a problem. See [ticket:7630#comment:5 comment 5]
 above: the issue isn't the lifetime of the value of `((vec |
 boost::adaptors::reversed) | boost::adaptors::uniqued)`, it's the lifetime
 of the ''subexpression'' `(vec | boost::adaptors::reversed)`, which is not
 bound to a local reference, and so does not have its lifetime extended.
