I'll elaborate
sub fudge($){ print @_ }
that is a function declaration -- it doesn't print anything
fudge(1);
fudge 2;
those are function calls, it prints 1 then prints 2
If you wrote
fudge 1,2;
the prototype ($) ensures fudge only gets 1 argument
If you try to force the issue with
fudge(1,2);
You'll get an error
$ perl -le " sub fudge($){print @_} fudge(1,2);
Too many arguments for main::fudge at -e line 1, near "2)"
Execution of -e aborted due to compilation errors.
Next time, when you get links, follow them, read them, its what we all do :)
