Dfr:
I searched through various D documentation sources and did not found anything except 'std.copy', but it's only for slices. Is there such feature in standart library ? Or some easy way to clone for example map of slices of maps or an object with few structs inside ?
I think such functionality is not yet present in Phobos, probably because it's not a common need. What is your use case?
