* module/oop/goops/describe.scm (describe): Remove commented code.
* module/oop/goops/save.scm (get-set-for-each, access-for-each): Update
these hoary routines for the new <slot> universe.
* libguile/goops.c (SCM_GOOPS_UNBOUND, SCM_GOOPS_UNBOUNDP): Remove
internal macros.
(scm_make_unbound, scm_unbound_p): Remove internal functions.
(scm_sys_clear_fields_x): Add "unbound" parameter, for the init
value.
* module/oop/goops.scm (*unbound*): Define in Scheme as a simple
heap-allocated value.
(unbound?): New definition.
(%allocate-instance): Pass *unbound* to %clear-fields!.
(make-class, slot-definition-init-value)
(slot-definition-init-form, make-closure-variable): Use *unbound*
instead of (make-unbound), which is now gone.
* module/oop/goops/active-slot.scm (compute-get-n-set): Use *unbound*
instead of make-unbound. This module uses the GOOPS internals module;
perhaps we should export make-unbound or something...
* module/oop/goops/save.scm (make-unbound): Export our own make-unbound
definition, for use by residualized save code.
* module/language/ecmascript/base.scm (<undefined>, *undefined*): Use a
unique object kind and instance for the undefined value.
* libguile/vm.c (scm_i_vm_mark_stack): Fill the stack with
SCM_UNSPECIFIED instead of SCM_UNBOUND.
* module/oop/goops/util.scm: Removed. Instead we fold these definitions
into goops.scm.
* module/oop/goops/save.scm: Remove useless import of util.scm.
* module/oop/goops.scm: Fold in util.scm. Since we always use
add-interesting-primitive!, import (language tree-il primitives) in
the header. Clean up some early comments, and use of eval-when.
* module/Makefile.am: Adapt.
* module/oop/goops/save.scm (write-component)
(write-component-procedure): Move definitions up so that syntax
definition is available when compiling the rest of the file.
* module/ice-9/channel.scm (eval): Fix number of arguments to
`guile:eval'.
* module/oop/goops/save.scm (write-readably): Fix number of arguments to
`write-array'.
* module/srfi/srfi-19.scm (priv:char->int): Fix number of arguments to
`priv:time-error'.
* libguile/eval.c (scm_m_eval_when): Whoops, eval-when has an implicit
begin. Fix.
* module/oop/goops.scm: Syncase doesn't like definitions in expression
context, and grudgingly I have decided to go along with that. But that
doesn't mean we can't keep the old semantics, via accessing the module
system directly. So do so. I took the opportunity to rewrite some
macros with syntax-rules and syntax-case -- the former is nicer than
the latter, of course.
* module/oop/goops/save.scm: Don't define within an expression.
* module/oop/goops/simple.scm (define-class): Use define-syntax.
* module/oop/goops/stklos.scm (define-class): Use define-syntax.
Moved ice-9/ and oop/ under module/, with the idea being that we have
only scheme under module/. Adjusted configure.in and Makefile.am
appropriately. Put oop/ at the end of the compilation order.
