I had no doubt of that. My doubt is about set-cdr!.
sorry, i wasn't clear: "using cdr" should be "using the cdr", i.e., read
via "cdr", write via "set-cdr!".
I don't see that in the 1.6.0 manual, so I'll assume it was added
later.
see 1.4.1.91 manual, which derives from 1.5.7 and HEAD, mostly. the
referenced portion is part of the hash*-get-handle docstrings harvested
automagically from libguile/hashtab.c by "make" in doc/ref/.
Changes to the cdr of a handle (e.g., via set-cdr!) will be
reflected in future lookups for the same key. Changes to the car
of a handle (e.g., via set-car!) may cause future lookups to fail.
or, "behavior after changing the car of a handle is unspecified."
