2753	Please let array::swap call boost::swap, instead of std::swap_ranges	niels_dekker	No-Maintainer	"The {{{swap}}} member function of {{{boost::array}}} is implemented by calling {{{std::swap_ranges}}}. Now I've looked into various STL implementations, and some of them have {{{swap_ranges}}} doing element-wise copying, even when the the element type has a custom {{{swap}}} function. So it appears be preferable to have {{{array::swap}}} call {{{boost::swap}}} instead, for each of its elements. 

The [http://www.boost.org/libs/utility/swap.html boost::swap utility], provided by Joseph Gauterin, takes care of calling the appropriate custom {{{swap}}}, whenever found by argument-dependent lookup (ADL).  Moreover, it also supports swapping built-in arrays.

So please consider applying the attached patch."	Patches	closed	Boost 1.39.0	array	Boost 1.38.0	Optimization	fixed		niels_dekker
