If you need a generalized deep copy, one can be cobbled with the gob package, which does type safe serialization~~, and an os.Pipe~~. The deepcopy function shown below works on arbitrary data with a few limitations. It handles data types with recursive or cyclic definitions, but does not handle cycles in the data itself. For example, it handles a linked list, but not a ring data structure. Another limitiation is that struct fields must be exported. (That is, fields must start with an upper case letter. This makes the field visible outside the package.)
