I don’t think there is such a function, but I’m also not sure what you want as a return type?

11/07/2017, 7:36 AMthe return type would be a collection that contains the elements that were flat mapped as well as the remaining unmapped elements. so a collection of elements, not a collection of collections

11/07/2017, 9:19 AMi should probably also mention the function i'm flatmapping is going to return the same type. sort of like if i had a list of tree nodes and the flatmap operation was to get the child nodes

It looks more like tree traversal sequence, which can be implemented much more efficient than creating a list.
