scm_copy_tree is too much, since it makes the following code fail: (let ((a '(1 2 3))) (letrec ((x a) (y a)) (eq? x y))) We should not copy the values themselves, just the storage cells; thus, scm_list_copy is the right thing here. But should we make that change? I am not sure. It causes some significant run-time overhead for an obscure benefit. For now I'll just put in some comments in eval.c and r5rs_pitfall.test. -- GPG: D5D4E405 - 2F9B BCCC 8527 692A 04E3 331E FAF8 226A D5D4 E405 _______________________________________________ Guile-devel mailing list Guile-devel@gnu.org http://lists.gnu.org/mailman/listinfo/guile-devel
