Hi,
Is there an interest in a scoped_ptr that receives a Allocator parameter?
I don't understand. I didn't think scoped_ptr did any allocations.
It doesn't, but it calls delete. Which is not appropriate when using an Allocator. Though a make_scoped_ptr would be quite handy too for a scoped_ptr with Allocator support.
then you're looking for a deleter, as implemented by boost shared_ptr. I'm not sure what the benefit would be of implementing a deleter for scoped_ptr. deleters execute arbitrary code when the contained object is deleted. for a scoped_ptr, that code already has a place to go: a destructor. scoped_ptr just automates the common behaviour of a destructor, deleting an exclusively owned pointer. if you need to do something else, you can do so in a destructor.
