Hi,
killer feature for me is possibilities to interact with running system.

You can send arbitrary messages to arbitraty processes, call arbitraty
functions, restart anything by hand. This gives utmost flexibility to
inspect and fix a running system.

$ erl -setcookie company_name -sname d

true

{still_alive, [some, stuff], but_soon_will_die, [why]}. ...
