I was under the impression that #:renamer should give us enough rope
to shoot anyone in the foot ;-)
A quick and unscientific test -- this one should rename xcons to snoc
and leave all the rest of srfi-1 alone:
tomas@trotzki:~$ guile
GNU Guile 3.0.9.120-79e836-dirty
Copyright (C) 1995-2023 Free Software Foundation, Inc.
scheme@(guile-user)> (use-modules ( (srfi srfi-1)
#:renamer (lambda (sym)
(if (eq? sym 'xcons)
'snoc
sym))))
scheme@(guile-user)> (snoc 'a 'b)
$1 = (b . a)
Cheers
