 Lambda Forms
 ------------
 
-By popular demand, a few features commonly found in functional programming
-languages like Lisp have been added to Python.  With the :keyword:`lambda`
-keyword, small anonymous functions can be created. Here's a function that
-returns the sum of its two arguments: ``lambda a, b: a+b``.  Lambda forms can be
-used wherever function objects are required.  They are syntactically restricted
-to a single expression.  Semantically, they are just syntactic sugar for a
-normal function definition.  Like nested function definitions, lambda forms can
-reference variables from the containing scope::

+is to pass a function as an argument::
