Hi Niels,
[It's] not recommended to do an unqualified call to boost::swap:
std::string a1[42]; std::string a2[42];
boost::swap(a1, a2); // Okay.
using boost::swap; swap(a1, a2); // Does not compile!
why do you think this code won't compile? As far as I can tell, ADL would resolve the call to invoke std::swap(). In fact, ADL is the very reason why some people recommend the exact opposite of what you've been saying, i.e. swap() should always be called unqualified.
They recommend that swap be called unqualified and ADL used in the context of working around the limitations of std::swap. boost::swap on the other hand handles the ADL internally. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEARECAAYFAkpI0xoACgkQ5vihyNWuA4W91QCgz4XGn+jpGf3GUSN0u4K9NUAZ cm0AoJRs/ghIj8Be+QoLsCeSj6gYxsdc =8AkT -----END PGP SIGNATURE-----
