The "return" keyword is not needed if the right hand side of the lambda arrow ("==>") is an expression that is not wrapped in curly braces.

If the right hand side _is_ wrapped in curly braces then it is treated as a list of statements, in which case you do need to use the "return" keyword.

Edit: My previous comment was referring to the second occurrence of "return" in your example (after the "==>" arrow). Just noticed I mistakenly dropped the first occurrence of "return"; the first occurrence of "return" in your example is needed.
