Ruby copied this feature from Perl, which copied it from Unix shells. (I will not attempt to untangle the history of Unix shells in order to figure out which one invented this.) I’m not necessarily saying it’s a good idea, but programming systems have been doing this for at least thirty years, and likely forty or more. There’s ample precedent.
