* 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.
