      Description

        Many existing scripts, especially node modules, use 'const' and so fail on Nashorn. As far as I can tell, a simple string replace with 'var' works just fine, but obviously Nashorn can do this much more effectively.

        A new Options argument (even undocumented) would be perfect, e.g.

        nashorn.option.const.as.var = {
            name="--const-as-var",
            is_undocumented=true,
            desc="Replace 'const' with 'var'.",
            type=Boolean
        }

        FWIW, our use case would pass it via NashornScriptEngineFactory.getScriptEngine().
