It is very powerful and based on the MVEL language (note you can also use JavaScript, Groovy, Python and Ruby).   provides a very easy way to access the current message in a flow, write conditional filters and perform content based routing.  The MEL Cheat Sheet, gives you an overview of the commands you can use.  -- David Dossot 


Now there's an official MuleSoft cheat sheet for the Mule Expression Language.  You ought to check it out if you're a Mule ESB user, or looking for an ESB based on the ease of their processing flows.
