39.14 SRFI-17 - Generalized set!
================================
This is an implementation of SRFI-17: Generalized set!
It exports the Guile procedure `make-procedure-with-setter' under
the SRFI name `getter-with-setter' and exports the standard procedures
`car', `cdr', ..., `cdddr', `string-ref' and `vector-ref' as procedures
with setters, as required by the SRFI.
SRFI-17 was heavily criticized during its discussion period but it
was finalized anyway. One issue was its concept of globally associating
setter "properties" with (procedure) values, which is non-Schemy. For
this reason, this implementation chooses not to provide a way to set
the setter of a procedure. In fact, `(set! (setter PROC) SETTER)'
signals an error. The only way to attach a setter to a procedure is to
create a new object (a "procedure with setter") via the
`getter-with-setter' procedure. This procedure is also specified in the
SRFI. Using it avoids the described problems.
