This would be nice for some kinds of tracing. We have a Perl Trace library at
work which prints the method's arguments, and is used like this:

    su foo {
      my($arg1, $arg2) = @_;
      Trace::begin(@_);
      ...
    }

No easy way to do this in Ruby beyond

    Trace.begin(arg1, arg2)

Instead I'd like to be able to write

    Trace.begin(__argv__)

or something like that...
