Fix @ and @@ to not capture lexicals; new @@ @@ form for R6RS libraries
* module/ice-9/psyntax.scm (@): Return top-wrap instead of the wrap
applied to the '@' form, so that the symbol will be interpreted as a
top-level identifier and never refer to any lexical variable.
(@@): Change the syntax used to support R6RS 'library' forms to:
(@@ @@ (mod ...) body). Change the behavior of the documented
(@@ (mod ...) id) form to be the same as that of @, except for the use
of 'private' instead of 'public' in the psyntax mod: use syntax->datum
on the identifier, and return top-wrap instead of the wrap applied to
the '@@' form.
This fixes <http://bugs.gnu.org/10756> reported by Ludovic Courtès.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/r6rs-libraries.scm (library): Use '@@ @@' syntax instead
of the older '@@' syntax.
* test-suite/tests/syncase.test (changes to expansion environment): Use
'@@ @@' syntax.
* module/Makefile.am: Add explicit dependencies for boot-9.go on the
files that it includes: quasisyntax.scm and r6rs-libraries.scm.
