* 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/language/ecmascript/base.scm (->boolean): Call `zero?' and
`nan?' only when X is a number.
* test-suite/tests/ecmascript.test ("compiler"): Add test case.
* module/language/ecmascript/base.scm (prop-keys): New method, returns
the list of keys of props of this instance.
* module/language/ecmascript/impl.scm: Refactor the global object into a
special kind of module object. Provide a prop-keys implementation for
module objects.
* module/language/ecmascript/compile-ghil.scm (comp): Compile for-in.
* module/language/ecmascript/impl.scm: Reshuffly things, and implement
make-enumerator, a helper for use in for-in statements.
* module/language/ecmascript/parse.scm (parse-ecmascript): Fix parsing of
for (var foo in bar) {}...
* module/language/ecmascript/array.scm (*array-prototype*): Declare the
constructor.
* module/language/ecmascript/base.scm (pput, pdel): Remove some needless
checks.
(new): Move definition of new here, and use the constructor.
* module/language/ecmascript/compile-ghil.scm (compile-ghil): Add a stub
so that when we load a compiled JS program, we make sure the runtime
has been booted.
* module/language/ecmascript/function.scm (js-constructor): Export a
js-constructor method instead of a new method.
* module/language/ecmascript/impl.scm (<js-global-object>): Define a new
class for the global "this" object, wrapping bindings from the current
module.
(init-js-bindings!): Define the dozen or so global properties, in the
current module.
(+): Define addition operations for non-numbers. This is efficient
because the generics are only dispatched if the fast-path fails.
* module/language/ecmascript/base.scm: Implement some more robust
property getters that convert strings to symbols. Implement
has-property?.
* module/language/ecmascript/compile-ghil.scm (comp): Implement lots more
mathematical operators. We now do all expressions; on to statements.
* module/language/ecmascript/impl.scm: Define some math helpers. They
probably need to call ->number on some things.
* module/language/ecmascript/parse.scm (parse-ecmascript): Fix a typo.
* module/language/ecmascript/base.scm:
* module/language/ecmascript/compile-ghil.scm:
* module/language/ecmascript/impl.scm:
* module/language/ecmascript/parse.scm: Compile "method calls" in such a
way that "this" gets propagated correctly.
* module/language/Makefile.am:
* module/language/ecmascript/impl.scm:
* module/language/ecmascript/array.scm:
* module/language/ecmascript/base.scm:
* module/language/ecmascript/function.scm: Split out the runtime into
different files. Implement more of the spec's runtime.
