This SRFI proposes
(write-with-shared-structure) and
(read-with-shared-structure), procedures for writing and reading
external representations of data containing shared structure. These
procedures implement a proposed standard external notation for data
containing shared structure.
This SRFI permits but does not require
replacing the standard (write) and (read) functions.
These functions may be implemented without the overhead in time and space
required to detect and specify shared structure.
An implementation conforms to this SRFI if it
provides procedures named (write-with-shared-structure) and
(read-with-shared-structure), which produce and read the same
notation as produced by the reference implementation. It may also provide
(read/ss) and (write/ss), equivalent functions with
shorter names.
