Hello, Glen Fernandes has kindly contributed an implementation of make_shared_array and allocate_shared_array. These are like make_shared and allocate_shared, except that they take a size_t argument N and allocate an array of N elements. Glen has made the functions return a shared_ptr, mostly because they are non-intrusive and it's not possible to return a shared_array without changes to shared_ptr and shared_array. But we can make such changes when we put the functions in Boost. So the question is, should we? It makes almost no sense to have a function called make_shared_array that does not, in fact, make a shared_array. On the other hand, Glen posits that some people may prefer to use shared_ptr instead of shared_array in their code for various reasons, one of which is that shared_array's default constructor can throw. Opinions?
