Sure: serialize (or pickle, or marshal) simply means to get a flat
representation of a data structure. For example, you could say computer
programs are seralized representations of the parse trees.
I think the term pointer-isomorphism should be obvious: a non-formal
definition wouild be to say that there is a mapping between the addresses
such that one structure goes into the other.
Any real language (as opposed to glorified assemblers (C++) or macro
processors (Tcl/bash)) has a built-in serialize and deserialize mechanism:
Java (implements serializable)
Python (pickle)
Perl (Data::Dumper)
Scheme (write)
This is a cool way to implement RPC, persistent objects, etc.
