-// Note: the implementation of this utility contains various workarounds:\r
-// - swap_impl is put outside the boost namespace, to avoid infinite\r
-// recursion (causing stack overflow) when swapping objects of a primitive\r
-// type.\r
-// - swap_impl has a using-directive, rather than a using-declaration,\r
-// because some compilers (including MSVC 7.1, Borland 5.9.3, and\r
-// Intel 8.1) don't do argument-dependent lookup when it has a\r
-// using-declaration instead.\r
-// - boost::swap has two template arguments, instead of one, to\r
-// avoid ambiguity when swapping objects of a Boost type that does\r
-// not have its own boost::swap overload.\r
