Subject: su {block of code.}

Hi!

Scenario: on a Unix-like system I run a ruby program under a
non-privileged user. Occasionally I need to gain root privileges.

For external commands it's just a matter of installing sudo, editing
/etc/sudoers properly, and going:

    system "sudo command..."

But what if I want to do the same for a block of code?

Something like this would be really, really cool:

    include Sudo
    su do
      # ruby code...
    end

There's a way to get this? A gem? Any idea on how to implement it?

Thanks,
Guido
