Why -- when supplying jjs script arguments?

[Cay Horstmann]

Hi, I am writing a chapter on Nashorn for "Java 8 for the Impatient", 
which will eventually find its way into one of the Core Java tomes.

I am a bit baffled why one needs to supply -- when calling a script with 
arguments. I mean, when I put a

#!/usr/bin/jjs

in a script, why can't I just run it as

myScript arg1 arg2 arg3

instead of

myScript -- arg1 arg2 arg3

I know I can solve this with a second script, but it seems a hassle. And 
is this a new thing? The article 
http://benjiweber.co.uk/blog/2013/01/27/javascript-shell-scripting-with-nashorn/ 
doesn't mention it.

Thanks,

Cay
