* module/language/ecmascript/parse.scm (parse-ecmascript): And update the function declaration forms for the new var syntax. * module/language/ecmascript/compile-ghil.scm (comp): Support foo["bar"] in addition to foo.bar. * module/language/ecmascript/impl.scm (pget, pput): Some fixes for when we get non-symbols -- it can happen, yo. I suppose we should allow for non-string keys too..
