> One more question – what are lambdas? 😉

Another name for anonymous functions - functions declared on the fly  
without assigning them to some method or top-level variable.

JavaScript example:  
// The argument to the ‘each’ method here is an anonymous function.  
myArray.each( function(i){ alert(i) } );

Ruby example:

# I’m making a brand new proc on the right side here

dir\_watcher.on\_modified = lambda{ |x| puts x }
