To generalize, a lambda function is a function that takes any number of arguments (including optional arguments) and returns the value of a single expression. lambda functions can not contain commands, and they can not contain more than one expression. Don't try to squeeze too much into a lambda function; if you need something more complex, define a normal function instead and make it as long as you want.
