* 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.
