// boost::swap internally does an unqualified function call to swap.
|
|
// This could have led to ambiguity or infinite recursion, when the
|
|
// objects to be swapped would themselves be from the boost namespace.
|
|
// If so, boost::swap itself might be found by argument dependent lookup
|
|
// (ADL). The implementation of boost::swap resolves this issue by
|
|
// using a barrier namespace. The following test checks this "ADL barrier".
