I wonder about possibly having some magic that would automatically

case for this for 'define-reader-ctor' feels quite strong. For the
load path case, it feels too hacky to try to recognize patterns like
(set! %load-path (append %load-path ...))', but perhaps OK if we
defined an 'add-to-load-path' procedure and applied the magic to that.
We already have an 'add-to-load-path' syntax. That way it doesn't need
any special magic since it can just expand to an `eval-when' usage
Ah, good, thanks for pointing that out.
but
apparently for some reason it doesn't do that at the moment (2.0.11):
scheme@(guile-user)> ,expand (add-to-load-path "foo")
(set! (@@ (guile) %load-path)
((@@ (guile) cons) "foo" (@@ (guile) %load-path)))

I'm not sure what that demonstrates. add-to-load-path _does_ appear to
work for me as hoped (and documented) when used in a situation like that
of the recent ossaulib thread - i.e. where a top level script wants to
extend the load path and then load modules from there:
-----------ctest.scm------------
(define-module (ctest)
#:export (square))
(define (square x) (* x x))
-----------ctest.scm------------
-----------ctst.scm------------
(add-to-load-path "/home/neil")
(use-modules (ctest))
(display (square 5))
(newline)
-----------ctst.scm------------
