Re: [boost] [swap] please update documentation with the header I need to include

[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().

Try it.
