Browse Source 
Refactoring in detail array_deleter before adding support for special-casing trivially default-constructible construction and trivially destroyable destruction.
........
Special case array construction for trivially default-constructible types and array destruction for trivially-destroyable types.
........
Optimization in initialization overload of array_construct for compilers to optimize it into the equivalent of a memset
........
Correctly use r-value reference semantics for Args and T in array utilities
........
Change ordering of overload definitions in array_utility.hpp
........
Convert function parameter for inner array size into template parameter and make identifiers in array_deleter consistent with those in array_utility 
........
