* libguile/vm-engine.h (POP_CONS_MARK): New macro, analagous to POP_LIST_MARK; used in quasiquote on improper lists. * libguile/vm-i-system.c (cons-mark): New instruction. You know the drill, remove all your .go files please. * module/system/il/compile.scm (codegen): Compile quasiquoted improper lists with splices correctly. Additionally check that we don't have slices in the CDR of an improper list. * testsuite/t-quasiquote.scm: Add a test for unquote-splicing in improper lists.
