6. Notes

6.1 Backend Designators

The backend argument to store, restore and with-backend is a backend designator which can be one of.

• A backend returned by (find-backend name)
• A symbol designating a backend (the first argument to defbackend).

6.2 Known Issues

• CLISP, OpenMCL, Allegro CL cannot store structure instances.
• Structure definitions are only supported in SBCL and CMUCL.
• Due to the fact that function's aren't fully supported CLOS Classes initfunction slot cannot be serialized.

6.3 Regarding String Serialization

Users are required to be extremely careful when serializing strings from one lisp implementation to another since the array-element-type will be tracked for strings and the Hyperspec does not specify an upper limit for base-chars. This can be a problem if you serialize a simple-base-string containing wide characters, in an implementation which specifies no limit on base-char, to an implementation with a limit. If you have a solution I would be happy to hear it.
