From my previous language (PHP) I could easily write function like this

if (empty($var))

even if the $var is not declared..

I thought in Ruby it will work the same way

if var.empty? (but empty is only in the String) so I thought something 
like this would solve it.

if var.to_s.empty? (object to string)

this didn't work either, but object had the nil method which could be 
used :)

if var.nil?

this didn't work either ..

so in Ruby everything is object if it was declared before :P o
