#12372: property_tree::get_optional without the template parameter

 Is it possible to call

 tree.get_optional<Data>(path)
 without the <Data> ?
 Note that Data is the type of the tree's Data.

 Would also be nice to be able to get the data as a pointer so that data
 can be updated in-place instead of get/push.

 Like this, implemented as a free function (for the non-const variant):

 Data * get_dataptr_optional( Tree & tree, string const& path )
 {
    if (optional<Tree &> node = tree.get_child_optional(path))
       return &node->data();
    return NULL;
 }

 cheers,
 Paul
